<section id="isPasted"><h2>Understanding Underwater Navigation</h2><p>In the navigation of underwater environments, knowing your position is critical, yet traditional Global Positioning System (GPS) solutions are rendered ineffective due to the limitations of underwater signal propagation.</p><p>In such challenging conditions, Deep Trekker’s Remotely Operated Vehicles (ROVs), equipped with a suite of advanced sensors and navigation methods, offer a sophisticated alternative.</p><p>Underwater navigation presents unique challenges owing to the attenuation and distortion of signals underwater, necessitating the development of specialized techniques. Deep Trekker ROVs leverage a diverse &amp; robust sensor suite as well as sensor fusion algorithms to navigate in these complex environments. This article examines the complexities of underwater navigation, demonstrating the role of Inertial Measurement Units (IMU), Ultra-Short Baseline (USBL), Doppler Velocity Log (DVL), Dead Reckoning, and other cutting-edge technologies employed by Deep Trekker ROVs.</p></section><section><h2>Key Underwater Navigation Sensors</h2><p>ROVs integrate a comprehensive suite of advanced sensors and methodologies, each playing a crucial role in ensuring reliable underwater navigation. Below is an overview of key sensors</p><p><strong>Camera:</strong> Serving as the primary source of situational awareness, high-definition cameras provide operators with real-time video feeds. They facilitate easy maneuverability during inspections of underwater assets and structures, offering vital visual cues essential for navigation.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226099378-1721226099378.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"><strong>Inertial Measurement Unit (IMU):</strong> Incorporating a compass, gyroscope, and accelerometer, the IMU tracks the ROV's orientation and motion in three-dimensional space. This data is necessary for stabilizing the vehicle and executing careful maneuvers.</p><p><strong>Pressure Sensor:</strong> Accurate depth measurement capabilities enable ROVs to maintain consistent altitude above the seabed, ensuring safe navigation and inspection operations. The depth / pressure is used to maintain a precise depth below the surface of the water column. The DVL also measures the altitude (vertical distance from the seabed).</p><p><strong>Doppler Velocity Log (DVL):</strong> By measuring changes in sound wave frequencies, DVL systems determine the ROV's speed, direction, and altitude relative to the seabed. This information is vital for maintaining course accuracy and executing dynamic maneuvers.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226094348-1721226094348.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></p><p><strong>Multibeam Imaging Sonar:</strong> Utilizing sound waves for real-time imaging, multibeam sonars offer detailed underwater visibility even in low or zero-visibility environments. They play a crucial role in navigation, object detection, and seabed mapping with exceptional resolution, serving as the primary visual aid when water clarity is compromised.</p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226097757-1721226097757.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"><p><strong>Ultra-Short Baseline (USBL):</strong> Integration with USBL enhances navigation accuracy and enables autonomous navigation and position holding in challenging underwater conditions.</p><p><strong>Dead Reckoning:</strong> Dead Reckoning is a fundamental navigation method to estimate position based on previously known position, velocity, and heading information. By continuously integrating sensor data and accounting for external factors such as current drift, Dead Reckoning algorithms enable ROVs to maintain correct position estimates over extended mission durations.</p><h2>USBL Integration: Achieving Underwater Navigation Precision</h2><p>The integration of USBL systems transforms underwater navigation, offering exceptional accuracy and reliability. By triangulating the ROV's position relative to surface transducers, USBL technology enables real-time mapping and localization underwater.</p><p>The seamless integration of USBL positioning enhances the capabilities of underwater ROVs, providing users with comprehensive navigation and mapping solutions tailored to diverse underwater applications.</p></section><section><p>USBL triangulation quality is not as accurate compared to GPS triangulation quality; however, the overall quality of USBL is improved through sensor fusion.</p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226101337-1721226101337.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"><h2>Exploring IMU Technology</h2><p>IMUs are integral components of underwater navigation systems, providing crucial data on an ROV's orientation and motion.</p><p>Let’s take a look at both FOG and MEMS based IMU systems.</p><h3>MEMS vs. FOG IMU: Choosing the Right Technology for Underwater Navigation</h3><p>In the world of underwater navigation, the selection of the appropriate IMU technology plays a crucial role in ensuring accurate positioning and stable control of ROVs. Two prevalent IMU technologies, Microelectromechanical Systems (MEMS) and Fiber Optic Gyroscope (FOG), offer distinct advantages and trade-offs, each suited to specific applications and operational requirements.</p><h3>MEMS IMU: Miniaturization and Cost-Efficiency</h3><p>MEMS IMUs are characterized by their compact size, low power consumption, and cost-effectiveness.</p><p>Leveraging microfabrication techniques, MEMS IMUs integrate miniature sensors, including accelerometers and gyroscopes, onto a single silicon chip. This miniaturization enables MEMS IMUs to be seamlessly integrated into compact ROV designs, offering enhanced maneuverability and operational flexibility.</p><p><a href="https://www.deeptrekker.com/shop/products/sensor-pod" target="_blank"><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226108646-1721226108646.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></a></p><p>Furthermore, MEMS IMUs boast relatively lower production costs compared to their FOG counterparts, making them an attractive choice for budget-conscious projects and applications requiring mass deployment of underwater vehicles.</p><p>Despite their compact size and cost-effectiveness, MEMS IMUs deliver respectable performance in terms of accuracy and reliability, meeting the demands of many underwater navigation tasks.</p><p>One of the main drawbacks of MEMS is that they are less stable compared to FOG systems. MEMS systems usually rely on a compass to ensure heading stability. This fixes the heading stability issue while maintaining cost-effectiveness, however, this also means that MEMS systems tend to be susceptible to local magnetic distortions.</p><h3>FOG IMU: Precision and Stability at a Higher Cost</h3><p>In contrast, FOG IMUs offer exceptional precision and stability, making them well-suited for demanding underwater navigation applications that require more finite accuracy and long-term reliability. FOG IMUs utilize the principles of interferometry, where light waves traveling through a coiled fiber optic loop experience changes in phase due to rotation, allowing for accurate measurement of angular velocity.</p><p>The inherent stability and accuracy of FOG IMUs make them ideal for tasks such as underwater mapping, seabed surveying, and pipeline inspection, where positioning and motion tracking are critical. However, FOG IMUs typically command higher production costs and exhibit larger physical footprints compared to MEMS counterparts.</p><p>In addition to their cost, it’s important to note that FOG IMUs also require a significant amount of time to boot up and calibrate (approximately 15 minutes). During this time, the vehicle must be completely flat and stationary on solid ground, which makes deployment off of a boat problematic.</p><h3>Choosing the Right IMU for Your Application</h3><p>When selecting between MEMS and FOG IMUs for underwater navigation, it is necessary to consider the specific requirements of the intended application, including accuracy, cost constraints, operational conditions, and deployment scale. For projects prioritizing compactness, cost-efficiency, and versatility, MEMS IMUs offer an attractive solution, providing great performance for a wide range of underwater tasks.</p><p>On the other hand, applications demanding uncompromising precision and long-term stability may favor the superior performance offered by FOG IMUs, despite their higher cost and larger form factor.</p><p>By carefully evaluating the trade-offs between performance, cost, and operational requirements, teams can make informed decisions when selecting the most suitable IMU technology for their underwater navigation needs.</p><p>While MEMS IMUs excel in compactness and cost-efficiency, FOG IMUs offer unmatched precision and stability, catering to the diverse needs of underwater inspections, research, and industrial applications.</p><p>By understanding the strengths and limitations of each IMU technology, stakeholders can make informed decisions to optimize the performance and efficiency of their underwater navigation solutions.</p></section><section><h2>Dead Reckoning Techniques</h2><p>Dead Reckoning serves as a complementary method for underwater navigation, particularly in scenarios where external positioning systems may be unavailable or unreliable.</p><p>By continuously integrating IMU data with velocity and heading information, dead reckoning algorithms estimate the ROV's position based on its previous known location. Deep Trekker ROVs utilize Dead Reckoning techniques to maintain navigation accuracy in sub-sea GPS-denied environments.</p></section><section><h2>ROV Navigation With Sonar</h2><p>With the unique profile of acoustic interpretation, sonar systems can be very valuable when mounted with an ROV. Without sonar, the pilot of the ROV will have to rely on the visual relay of the objects and features through a camera. In low visibility environments, it might be hard to see with the range often being under a meter.</p><p>Sonar systems will drastically increase this range, allowing the pilot to detect objects from much further away. Instead of going over the seabed to find objects, the ROV can remain stationary and scan the entire environment. The pilot can then get an understanding of the area with the man-made objects, natural surfaces, and areas to ignore.</p></section><section><h2>Sensor Fusion: Enhancing Navigation Precision</h2><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226111942-1721226111942.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii">The synergy of IMU, DVL, and other sensors through sensor fusion techniques enhances the accuracy and reliability of underwater navigation. By intelligently integrating data streams and compensating for sensor inaccuracies, ROVs achieve navigational precision and stability.<p>Sensor fusion algorithms optimize control responses, mitigate environmental disturbances, and enable autonomous operation, thereby streamlining underwater operations and inspection tasks.</p><p>Through continuous refinement and calibration, sensor fusion elevates the capabilities of Deep Trekker ROVs, ensuring seamless navigation even in dynamic underwater environments.</p></section><section><h2>Advanced Underwater Positioning Systems: A Comparative Analysis</h2><p>The classifications of positioning systems can be divided into three overarching tiers, each catering to specific requirements and budgets.</p><p>High-End Military Grade Solutions: "The high-end, military-grade solutions are typically FOG IMU-based, without the need for DVL integration, employing accelerometers and gyroscopes, albeit at a prohibitive cost," explains Nemanja Kliska, Deep Trekker Team Lead and Autonomy Systems Engineer.</p><p>These top-tier systems, typically priced between half a million to several million dollars, prioritize uncompromising accuracy and reliability. Utilizing FOG IMU-based technology, these systems, commonly found on military vessels and submarines, employ gyroscopes and accelerometers to achieve precise navigation without reliance on external sensors like DVL.</p><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1721226111248-1721226111248.png" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></p><p>AC Spark Plug Titan Inertial Measurement Unit</p><p><br></p><p><strong>High-End Civilian Systems:</strong> Positioned below military-grade solutions, high-end civilian systems offer advanced navigation capabilities at a relatively lower cost. Incorporating IMU or AHRS technology - comprising accelerometers, gyroscopes, and magnetometers - these systems ensure robust performance in various underwater environments. Moreover, some variants employ FOG systems to mitigate heading drift, enhancing positional accuracy.</p><p><strong>MEMS-based Systems:</strong> Representing the next tier, MEMS-based systems provide a cost-effective alternative with acceptable performance metrics. Integrating MEMS gyroscopes and accelerometers, these systems offer satisfactory accuracy under optimal conditions. However, they rely heavily on compass or magnetometer data and require continuous calibration to mitigate errors and environmental interference, and require the incorporation of DVL systems.</p></section><section><h2>Advancing Underwater Navigation with Deep Trekker ROVs</h2><p>In conclusion, the utilization of advanced sensors and positioning methods transforms underwater navigation with Deep Trekker ROVs.

MEMS vs FOG IMUs: Exploring Underwater Navigation Technology

<section id="isPasted"><h2>What is Dead Reckoning?</h2><p>Dead Reckoning navigation, also known as "deduced reckoning," relies on the principle of estimating the current position based on the last known position, velocity, and heading. It involves using the direction and speed of movement to calculate where you are now relative to where you were previously.</p><p>Dead Reckoning is particularly useful in scenarios where GPS signals are unreliable or unavailable, such as underwater environments where GPS signals cannot penetrate. This method has been integral to navigation, serving as a reliable means of orientation when other references are unavailable or unreliable.</p><p>“Dead reckoning is quickly becoming our new favorite way to operate ROVs and understand positioning of our vehicles,” says Sam Macdonald, President of Deep Trekker. “Setting up USBL or flying completely blind is hard for us as users and our customers. We want to make the piloting experience as easy as possible.”</p><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzIwMDI0OTgxMTkzLTE3MjAwMjQ5ODExOTMucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></section><section><h2>The Significance of Dead Reckoning in Underwater Navigation?</h2><p>There are numerous challenges with underwater navigation. Unlike terrestrial or aerial navigation, where landmarks or satellites provide reference points, underwater environments offer minimal visual cues.</p><p>Factors such as fluctuating ocean currents, variations in water density, and unpredictable underwater terrain further complicate the navigation challenges. Without reliable navigation, underwater vehicles run the risk of veering off course, potentially endangering both the vehicle itself and any onboard equipment or personnel.</p><p>Navigating underwater environments poses distinct challenges, requiring specialized techniques like Dead Reckoning to ensure safe and efficient operations. Underwater navigation lacks prominent landmarks or GPS signals, making reliance on Dead Reckoning a key method for accurate positioning.</p><p>This method, reminiscent of long-standing historical navigation practices, becomes particularly important in underwater operations where traditional navigation aids like landmarks or celestial bodies are inaccessible.</p><p>Understanding and implementing Dead Reckoning involves leveraging advanced sensors and algorithms to mitigate inherent challenges, such as sensor inaccuracies and cumulative drift. As technology progresses, optimizing Dead Reckoning capabilities becomes pivotal for enhancing underwater navigation.</p><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzIwMDI0OTgwNjMzLTE3MjAwMjQ5ODA2MzMucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"><p>Deep Trekker’s PIVOT and REVOLUTION ROVs can operate with Dead Reckoning utilizing an upgraded inertial measurement unit (IMU) and Doppler Velocity Log (DVL) sensor combined with our BRIDGE software. The goal of these ROV systems is to simplify the experience so customers can input an initial position and then get in the water and go. That doesn’t mean there aren’t any best practices you can leverage to optimize your experience! Below are some tips and tricks to assist with your ROV piloting.</p><h3>The 6 Rules of Dead Reckoning</h3><p>The <a href="https://www.usna.edu/Sailing/_files/documents/2019_OSTS_Documents/Navigation_101_05MAR19.pdf" target="_blank" data-lf-fd-inspected-kn9eq4roawkarlvp="true">"6 Rules of Dead Reckoning"</a> are guidelines used in navigation, particularly in maritime and aviation contexts, to ensure that an estimated position (Dead Reckoning position) remains as accurate as possible throughout a journey. These rules help navigators keep track of their position and make necessary adjustments. To effectively maintain the vessel’s Dead Reckoning position, the navigator should follow theses 6 rules:</p><p><strong>1. Regular Position Updates:</strong> Update the Dead Reckoning position at regular intervals, typically every hour on the hour. This helps account for changes in speed, course, and environmental conditions that may affect the estimated position. This periodic recalibration is essential for compensating for sensor drift, especially prevalent in underwater technology. Manual recalibration or resurfacing with GPS helps in correcting any deviations and maintaining accuracy.</p><p><strong>2. Adjustment after course changes:</strong> Following any alteration in the vehicle's course, promptly update the Dead Reckoning position to accommodate the modified trajectory. Utilize additional sensors such as a Doppler Velocity Log (DVL) sensor that tracks changes from the seafloor for underwater vehicles or Inertial Measurement Unit (IMU) sensors that track vehicle orientation changes to ensure alignment with the intended route.</p><p><strong>3. Adjustment after speed changes:</strong> Whenever there is a change in the vehicle's speed, it's also important to update the Dead Reckoning position immediately to help ensure that the calculated position remains accurate, considering the altered velocity.</p><p><strong>4. After every fix or running fix:</strong> A "fix" is a position obtained from external references, such as celestial observations, GPS, or terrestrial landmarks. A "running fix" is an ongoing series of fixes that helps refine the Dead Reckoning position. After obtaining either a fix or running fix, the navigator should update the Dead Reckoning position to incorporate this more accurate position information. In the case of an ROV, running fixes could be a GPS mounted on top that gets a fix whenever surfacing or a USBL getting pings during its dive. A fix also could be from a manual GPS input by the user when the ROV surfaces.</p><p><strong>5. After plotting a single line of position:</strong> A line of position is a navigational line that represents the possible positions of a vehicle at a specific time. It is determined using observations of celestial bodies, radar ranges, or other means. After plotting a single line of position, the navigator should update the Dead Reckoning position to account for this new piece of positional data.</p><p><strong>6. DR twice and label with Course and Speed:</strong> After every fix or running fix (repeated for emphasis). Reiterating the importance of updating the Dead Reckoning position after obtaining a fix or running fix. This ensures that the Dead Reckoning position continuously incorporates the most accurate position information available.</p><p><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzIwMDI0OTgxMDk5LTE3MjAwMjQ5ODEwOTkucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"></p><p>Fig. 1: Example of a Mercator chart style Universal Plotting Sheet used by the Navy for navigation.</p></section><section><h2>Integration of Dead Reckoning with Other Navigation Techniques</h2><p>While Dead Reckoning serves as a foundational navigation method and can be a standalone tracking method, its effectiveness can be amplified through integration with complementary techniques. By combining Dead Reckoning with other navigation methods, such as acoustic positioning systems and satellite-based navigation, navigators can enhance positional accuracy and resilience to environmental challenges.</p><p>Acoustic positioning systems, such as Ultra-Short Baseline (USBL), Short Baseline (SBL), and Long Baseline (LBL), provide precise localization capabilities by measuring the time of flight of acoustic signals between transponders and the vehicle. By incorporating acoustic position updates into Dead Reckoning calculations, navigators can refine their estimated positions and mitigate drift accumulation.</p><p>Similarly, satellite-based navigation systems, including GPS and GNSS (Global Navigation Satellite System), offer helpful external references for validating Dead Reckoning positions. While traditional GPS signals may be unavailable underwater, emerging technologies such as underwater GPS and Differential GNSS (DGNSS) enable precise positioning in submerged environments. By cross-referencing Dead Reckoning positions with satellite-derived fixes, navigators can ensure greater accuracy and reliability in their navigational estimates.</p><p>Furthermore, fusion algorithms, such as Deep Trekker’s Sensor Fusion algorithms, that integrate data from multiple sensors and navigation methods can optimize positional accuracy and robustness. By leveraging the strengths of each technique while compensating for their respective limitations, fusion algorithms provide a comprehensive solution for underwater navigation challenges.</p></section><section><h2>The Role of Sensors in Dead Reckoning</h2><p>Sensors play a significant role in Dead Reckoning by providing essential data inputs for calculating position estimates. Particularly in underwater navigation scenarios with ROVs, characterized by limited visual references, sensors serve as the eyes and ears of the vehicle, capturing crucial information about its movement and surroundings.</p><p>Various types of sensors are employed to track different aspects of the vehicle's motion. Doppler Velocity Log (DVL) sensors measure the vehicle's velocity relative to the seafloor by analyzing Doppler shifts in acoustic signals. This data is integral for calculating speed and direction changes, forming the basis of Dead Reckoning calculations. Additionally, Inertial Measurement Unit (IMU) sensors track the vehicle's orientation and angular velocity, providing necessary inputs for maintaining course accuracy.</p><p>Advancements in sensor technology, such as miniaturization and improved accuracy, have also enabled more sophisticated Dead Reckoning systems. MEMS (Micro-Electro-Mechanical Systems) sensors, characterized by their compact size and low power consumption, have become increasingly prevalent, offering a perfect blend of performance and efficiency for underwater navigation applications.</p><p>By leveraging the capabilities of these sensors, Dead Reckoning systems can navigate with improved precision, overcoming the challenges posed by the underwater environment and enabling safer and more efficient navigation.</p></section><section><h2>Understanding the Limitations of Dead Reckoning</h2><p>While Dead Reckoning serves as a valuable navigation technique, it is not without its challenges and limitations. Understanding these factors is important for mitigating risks and optimizing the performance of Dead Reckoning systems.</p><p>One notable challenge is the accumulation of errors over time, often referred to as "dead reckoning drift". This drift can arise from sensor inaccuracies, environmental disturbances, and uncertainties in the vehicle's dynamics. It’s important to note that these errors can compound, leading to considerable deviations from the true position, which is why periodic updates and recalibrations are so critical for maintaining accurate positional data.</p><img src="https://images.wevolver.com/eyJidWNrZXQiOiJ3ZXZvbHZlci1wcm9qZWN0LWltYWdlcyIsImtleSI6ImZyb2FsYS8xNzIwMDI0OTgxMTM4LTE3MjAwMjQ5ODExMzgucG5nIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjo5NTAsImZpdCI6ImNvdmVyIn19fQ==" alt="DESCRIPTION HERE" width="800" height="356" class="fr-fic fr-dii"><p>Dead Reckoning is also susceptible to disruptions caused by external factors such as ocean currents, water density variations, and submerged obstacles. These dynamic environmental conditions can impede the vehicle's trajectory, making it challenging to maintain accurate position estimates.</p><p>Additionally, reliance solely on Dead Reckoning in scenarios with limited external references, amplifies the risk of navigation errors. In such cases, a single miscalculation or sensor malfunction could lead to navigation errors with potentially serious consequences.</p><p>Addressing these challenges requires a multi-faceted approach, combining robust sensor technologies, advanced algorithms, and strategic operational practices. By continually refining Dead Reckoning systems and incorporating complementary navigation techniques, such as Deep Trekker’s Sensor Fusion algorithms, operators can navigate with greater confidence and reliability in challenging underwater environments.</p></section><section><h2>Dead Reckoning Empowering ROV Operations</h2><p>Dead Reckoning is a fundamental navigation technique, offering a practical solution for navigating the intricate and often unpredictable underwater terrains encountered by ROVs (remotely operated vehicles) used for underwater operations.</p></section><section><p>By leveraging known parameters and updating positions in responses to changes in course and speed, Dead Reckoning provides a practical means of estimating positions where traditional navigation aids may be unavailable or impractical.</p><p>Its integration with complementary technologies such as acoustic positioning systems enhances its accuracy and robustness, making it a valuable tool for underwater operations and inspection tasks.</p><p>As advancements in sensor technology and navigation algorithms continue, Dead Reckoning holds promise as a dependable navigation technique for conducting essential vessel inspections with improved precision and efficiency, even in challenging underwater environments.&nbsp;</p><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1720025957910-IMG_6444.png" style="width: 100%px;" class="fr-fic fr-dib"></p></section><section><h2>The Deep Trekker Advantage</h2><p>Deep Trekker ROVs, engineered with rugged industrial-grade materials, are designed for versatility and durability.

Prior to incorporating ROVs, the company primarily relied on dive teams to gather critical information about underwater conditions. Now, they bring their Deep Trekker DTG3 and PIVOT ROVs to every job.</p></section><section><h2>Enhancing Safety and Efficiency in Underwater Inspections: The Role of ROVs at Chapman Marine Inc.</h2><p>Chapman Marine Inc., one of Texas’ trusted commercial dive and underwater construction companies, has revolutionized the field of underwater inspections by incorporating Remotely Operated Vehicles (ROVs) into their routine operations. In this case study, we will explore how Chapman Marine utilizes ROVs to enhance safety and efficiency during pre-job, routine, and emergency inspections. By doing so, they have not only reduced costs but also improved the quality of deliverables and safety for their team and customers.</p></section><section><h2>The Challenge of Underwater Inspections</h2><p>Philip Wolfe, General Manager at Chapman Marine, highlighted a recurring challenge in their operations: "We get the information that there's a problem down there, we know we've got an issue, but we don't know what it is."</p><p>Often, their team receives limited information about underwater issues, making it difficult to assess risks accurately. This lack of clarity poses a significant safety hazard for divers. Ultimately, the ROVs are much faster, safer, and easier to deploy than a diver.</p></section><section><h2>The Solution: Leveraging ROVs for Comprehensive Underwater Inspections</h2><p><img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/2HlhtDflcr3ceNAxZXkicZ/8c6472960bb03f32ab1481c92057b8a9/image2.jpg" alt="Deep Trekker DTG3 ROV and tether reel package" class="fr-fic fr-dii"></p><p>Deep Trekker DTG3 ROV and tether reel package</p><h3>A Closer Look Before the Dive: ROVs Enhancing Safety in Pre-Job Inspections</h3><p>Before diving into the water, the team uses the limited information received from the customer to develop an initial understanding of the situation. This helps them gauge the safety risks involved.</p><p>“We use the ROVs to develop an understanding before we put divers in, to help us understand the safety risk before getting in the water,” Wolfe explains.</p><h3>Streamlining Routine Inspections: ROVs' Efficiency in Action</h3><p>ROVs are deployed for routine inspections, especially in confined spaces or areas requiring penetration. These inspections are completed in a fraction of the time it would take a dive crew, saving both time and resources.</p><p>“In some circumstances,” says Wolfe, “we use the ROV as the primary solution for certain inspections in areas where there's confined space or where we have to go into pipes or something like that, where it would take an entire day and a large crew to load out just to do the inspection, and we can do it in a few hours with the ROV and get the information that we need.”</p><h3>Responding Swiftly to Emergencies: ROVs in Critical Situations</h3><p>In emergency situations where immediate action is required, ROVs provide essential situational awareness. It’s dangerous to put divers into a situation where hazards aren’t entirely identified. Divers can be exposed to unknown dangers, making ROVs invaluable in understanding the situation better.</p><p>“We won't know all the safety issues. The ROVS help to develop the situation and we're often able to back off the urgency a little bit to say, ‘Here's the video. Here's what we understand. This is what we see is going on’. Then we pass that off to engineers, and make some recommendations so that they can develop that situation. So that's helpful for us and we're able to satisfy that gap in understanding in an emergency that often happens. It makes owners very uncomfortable, not knowing what's going on, and they want it fixed yesterday. So, it gives us some time to develop a better plan and then get out there and get after it.”</p><p><img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/2K5gmK7Ut4m7JK9qzINpgk/28dad4a5c6f8865d5f7246557bedf273/image1.jpg" alt="chapman case study dam" class="fr-fic fr-dii"></p></section><section><h2>ROVs vs. Tripod Mounted Sonar: A Paradigm Shift in Underwater Inspections</h2><p>Wolfe explained their preference for ROVs over a tripod mounted sonar (the current standard in the Gulf of Mexico for the oil industry that's used offshore when mapping and inspecting underwater assets), emphasizing the quick access ROVs offered to inspection sites. Tripod mounted sonar systems, while capable of producing high-quality images, required additional equipment and were less versatile.</p><p>“So, that was why we went with the ROV versus just a tripod mounted sonar, because of its very quick access to the site, where the tripod mounted sonar requires additional equipment to get there because it's not mounted to anything. It's a tripod, you need a boat and crew, you drop it down, and it sits on the bottom. You get a beautiful picture, but to get that beautiful picture, you have to have all that other stuff, and you have to have access to that point,” Wolfe illustrated.</p><p>“The limitations of a tripod mounted sonar is that it's not attached to an ROV, that it's not a two-man crew, and you have to have a boat. If you want GPS, you have to have that receiver attached to a boat. You have to do all this setup, which any GPS is going to require. I can't take a tripod mounted sonar with two guys and go 400 feet away from the shoreline when there's an issue on an intake or a dam or something. We need to have a place to launch, and all of these things that require additional equipment - which we have, but, It takes longer, it's more expensive, and a lot of times we just don't have direct access to the water - unless you're bringing ladders or you're doing a heck of a lot of work to get down there. If you're gonna do all that work, you might as well put a diver in the water.”</p></section><section><h2>ROVs in Action: Unveiling the Triad of Safety, Efficiency, and Quality</h2><p><img data-fr-image-pasted="true" src="https://images.ctfassets.net/kzewhs8e6cvu/740BJyCwuL4rDJcIdUIoo3/4c65a9c661ec75462cc06cfc9e703197/image3.jpg" alt="pelican case chapman " class="fr-fic fr-dii"></p><p>Chapman Marine has experienced numerous benefits since incorporating ROVs into their operations:</p><h3>Safeguarding Lives and Insights: How ROVs Prioritize Safety</h3><p>ROVs significantly reduce the risks associated with underwater inspections. Divers are no longer exposed to unidentified hazards, ensuring the overall safety of the team. “Anytime a diver enters without visibility, they are exposed to a risk that they don’t need to be if we run an ROV.”</p><h3>ROVs: The Turbocharged Engines of Inspection Efficiency</h3><p>Routine inspections that once took a full day to mobilize and deploy now require just a few hours with an ROV pilot, resulting in substantial time and cost savings.</p><h3>Delivering Clarity: ROVs and High-Quality Customer Communication</h3><p>ROVs provide high-quality video footage that can be shared directly with customers. This not only improves situational awareness but also allows customers to identify issues firsthand. “Visualization is the most important part of analysis,” explains Wolfe.</p><h3>Comprehensive Reporting: The Cornerstone of Effective Inspections</h3><p>After every inspection, whether performed by ROVs or divers, Chapman Marine produces comprehensive reports with videos, pictures, and descriptions of the work performed, and issues recommendations.</p><p>“When you're looking at the reports that we're putting together, what is good to decision makers, you're talking about the highest echelon of whatever organization that we're working for, and sending them a link to a video. They're not watching the video. They want a one to two page report that has a picture with a description. When you look at the executive level of making decisions on a project that we're working on, that's the type of report that we put together. It needs to be simple and very clear: ‘Here is what it looks like. Here's what your problem is.’ It is very helpful that the ROVs make producing reports very easy.”</p><h2>A New Era of Collaboration: ROVs Enhancing Customer Engagement</h2><p>Chapman Marine recognizes the importance of involving their customers throughout the inspection process. By utilizing ROVs, they can have their customer's eyes directly on live ROV surveys, aiding in issue identification. This customer-centric approach improves communication and helps solve problems more effectively. Previously, they had divers entering low visibility environments with regular cameras, or describing the situation for post inspection with hand drawings.</p><p>“The customer knows the original problem better than the divers. With an ROV video, we can have their eyes directly on the live ROV survey and can better identify issues rather than relying on diver descriptions. With ROVs we can get there fast, get the information, and get it in front of more eyes, quicker, to better solve the problem.”</p></section><section><h2>Deep Trekker: The Game-Changer in Underwater Inspections</h2><p><img data-fr-image-pasted="true" src="https://downloads.ctfassets.net/kzewhs8e6cvu/4H4NjDluiIL0HzoHj9U7RF/0aaf965ab8e7fe2b67793651ffd272ac/REV_Standalone.png" alt="REVOLUTION at Pier" class="fr-fic fr-dii"></p><p>transforming their approach to safety, efficiency, and customer satisfaction. ROVs have become indispensable tools that not only reduce costs but also enhance the quality of deliverables and the overall safety of their team. As Philip Wolfe succinctly puts it, "It's all about how to tell the customer what is happening," and ROVs have become their most valuable means of communication in the underwater inspection field.</p><p>When asked what he likes most about utilizing the Deep Trekker ROVs:</p><p>“Previous ROVs we have used required a lot of set up and programming that we just don’t have time for. With a Deep Trekker, I can plug it in and it’s ready to go, you do all the updates, and I can give it to somebody, give them some training, and then they can go out and execute.”</p><blockquote><p>It's not a science project every time we try to pass it off to somebody.</p></blockquote><p>So that's really what I'm looking for. I don't need a project. I've got enough projects. I just need something where I can take this and put it in the water now. I understand it takes work, there's a little bit of work, like building a report takes work, but there's different levels of work and there's a threshold at which I'm willing to go up to. But once it surpasses that threshold, it's just too much for us because it's too time consuming," explains Wolfe.</p><p>When asked why he stays with Deep Trekker:</p><p>“So, I will tell you, customer service for me is big. We're willing to pay a little bit more to have customer service because, in the end, that means saving time and money for us when we run into an issue - and that goes across everything that we do, whether we're buying a new engine for our boats, or whatever it is. We changed manufacturers for all the motors on our boats because there wasn't service for them. They're great motors, but no service doesn't help us. That's important, and I do like the updates. Deep Trekker just adds some additional capability to the ROV that you already have, to increase the functionality of the system. It’s awesome.”</p><h2>Exploring the Deep Trekker Family of ROVs</h2><p><img data-fr-image-pasted="true" src="https://downloads.ctfassets.net/kzewhs8e6cvu/5qr0cwf5B052kcAgyjmAH2/b3b3864cdf537fa3f718ccf8b045906e/Group_Glamor_Shot_2.png" alt="Family photo Group Glamor Shot 2" class="fr-fic fr-dii"></p><p>From left to right: DTG3, PHOTON, PIVOT, REVOLUTION</p><p>Deep Trekker ROVs present the ideal solution for conducting inspections of dams, infrastructure, and intake systems.

Making a 3D Model with Deep Trekker ROVs

<section id="isPasted"><h2>A Brief Introduction to Photogrammetry</h2><p>Photogrammetry, a word derived from "photo" (light) and "metry" (measurement), is the art and science of creating precise 3D models using 2D images. It's a technology that allows us to turn photographs into detailed and accurate spatial representations. In this article, we'll explore the fundamentals of photogrammetry and how it's transforming the way we perceive and measure the world around us.</p><h3>The Photogrammetry Process</h3><p>The photogrammetry process involves capturing multiple images of an object or scene from various angles and then digitally stitching them together to form a 3D model. To achieve this, specialized cameras or remotely operated vehicles (ROVs) with high-resolution sensors are often used. This section delves into the step-by-step process of acquiring the necessary images and the subsequent software-driven transformation into a 3D model.</p><h3>Why Use Photogrammetry</h3><p>Photogrammetry enables the creation of highly accurate 3D models and measurements, offering a versatile and efficient solution for capturing, analyzing, and visualizing spatial data. Its applications span across many industries such as:</p><ul><li><p><strong>Revolutionizing Surveying and Mapping</strong> Surveying professionals are increasingly turning to photogrammetry for its ability to create precise and detailed maps, improving the accuracy of measurements and simplifying the surveying process.</p></li><li><p><strong>Reshaping Architectural Design</strong> Architects and designers now rely on photogrammetry to bring their creations to life in a more detailed and accurate way, transforming architectural design processes and the benefits it offers in creating immersive 3D models.</p></li><li><p><strong>Preserving Cultural Heritage</strong> Photogrammetry has become an indispensable tool for the preservation of cultural heritage. By turning historical artifacts and sites into 3D models, we're not only preserving our past but also enabling future generations to explore and appreciate it.</p></li><li><p><strong>Entertaining with Precision</strong> In the entertainment industry, photogrammetry is revolutionizing special effects and game development, transforming the entertainment world and the incredible realism it brings to movies, games, and virtual environments.</p></li><li><p><strong>Forensics</strong> Forensic investigators are using photogrammetry to piece together crime scenes in remarkable detail, making a significant impact in the world of forensics and crime scene analysis.</p></li></ul><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1708454085651-1708454085650.png" alt="photogrammetry castle capture " class="fr-fic fr-dii"></p><p>Epic Games bringing the Ethiopian UNESCO site into 3D</p></section><section><h2>Acquiring Photogrammetry Footage: From Planning to Precise Capture</h2><p>Acquiring photogrammetry footage involves a structured process that varies depending on the specific application and available tools. To illustrate this process, let's explore underwater mapping as a specific example.</p><h3>Planning for Precision</h3><p>Before the cameras start rolling, meticulous planning is the cornerstone of a successful photogrammetry project. It begins by defining the target area or object, determining optimal camera positions and angles, and taking into account variables such as lighting conditions, water clarity, and turbidity. Effective planning sets the stage for accurate data capture.</p><h3>The Art of Capturing Images</h3><p>With a well-defined plan in place, the next step is to capture the images. In underwater mapping, this can be achieved through the use of remotely operated vehicles (ROVs) equipped with high-definition cameras or by deploying dive teams. The Deep Trekker ROV, for example, offers the convenience of the Mission Planner feature, enabling autonomous navigation along a predefined route while capturing images from multiple perspectives.</p><h3>Navigating the Perfect Path</h3><p>The chosen route for image capture can vary, from a spiral or wave pattern to straight paths, but the ultimate goal is to cover the largest possible area.</p><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1708454067087-1708454067087.png" alt="ROV possible route chart " class="fr-fic fr-dii"></p><p>Achieving the best footage often requires a complete 360-degree rotation around the object. For precision, maintaining substantial overlap (50% or more) between successive photos is crucial. Close-up shots enhance texture detail, while shots from a distance aid in seamlessly stitching the object together.</p><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1708454069683-1708454069683.png" alt=" ROV 360-degree rotation around a object" class="fr-fic fr-dii"></p><h3>Mastering Image Quality</h3><p>To ensure high-quality images, several factors come into play. Consistency in color balance is essential for accurate modeling. It's crucial to minimize movement of the ROV during image capture to prevent blurring and to avoid disturbing debris from the seabed. Utilizing fast shutter speeds minimizes motion blur, adjusting the aperture (high f-number) provides a broad depth of field, and lowering the ISO reduces noise in the images.</p><h3>Processing the Captured Images</h3><p>Once the images are in the can, the next step involves merging and processing them using specialized modeling software. This software employs algorithms to retain the details from each individual image, allowing it to create a point cloud—precise data about the size, area, and position of objects, like ship hull fragments. This point cloud serves as the foundation for mapping nodes or vertices onto a solid surface, ultimately forming the intricate mesh of the 3D model.</p></section><section><h2>How Does Photogrammetry Software Work</h2><p>Think of photogrammetry software as similar to putting together a 3D model. The computational task of photogrammetry is completed automatically in the background by the software, which analyzes the footage and identifies key features in each frame, including patterns or shapes. The first step, of course, is to ensure your image files are supported by the software you are using. From there, the process of turning images into a 3D model can be broken down into four primary steps:</p><h3>Step 1: Aligning the Visual Pieces</h3><p>The software's first task is to align the images in your dataset, precisely calculating their relative positions. This results in a set of images carefully coordinated to provide a clear and coherent perspective. It's during this step that the software begins to estimate depth information, assigning X, Y, and Z coordinates that will serve as the building blocks for the 3D model.</p><h3>Step 2: Constructing a Dense Point Cloud</h3><p>Once the images are aligned, the software creates a dense point cloud. This cloud is a virtual representation of the subject, populated with countless points, each holding both location and color information. These points collectively capture the intricate details of the subject, forming the foundation for a precise 3D model.</p><h3>Forging the Mesh</h3><p>Building on the point cloud, the software utilizes mesh generation techniques to connect the individual points together. Imagine this as a network of triangular polygons weaving the points into a coherent structure. This process is pivotal in shaping the subject's geometry within the 3D space.</p><h3>Crafting Photorealistic Texture</h3><p>Now bring the 3D model to life. The software draws upon color and texture data from the original images. It refines the model through texture mapping, infusing it with the hues and nuances of the real subject. This final step ensures that the 3D model not only captures the physical structure but also boasts a photorealistic appearance.</p><h2>Finding Footage for Photogrammetry</h2><p>Acquiring the right imagery for photogrammetry is a crucial aspect of creating accurate 3D models. The number of images needed depends on the subject's characteristics, including its size, shape, scale, and complexity. While intricate subjects demand hundreds of images captured from multiple angles, simpler objects may require only a handful.</p><p>Image resolution is a key determinant of photogrammetry quality. The resolution impacts the number of points that the photogrammetry algorithm can analyze, directly influencing the 3D model's precision and detail.</p><h3>Optimizing Image Requirements for Flawless 3D Modeling</h3><p>Achieving flawless 3D modeling through photogrammetry requires a meticulous approach to image requirements. Several factors come into play, including image resolution, overlap, camera settings, lighting conditions, and image acquisition angles. One critical factor is the subject's physical characteristics. Photogrammetry software excels with textured, multi-colored, and organic subjects. In contrast, smooth, shiny, single-colored, transparent, or mirrored subjects pose challenges for proper image reconstruction.</p><h3>The Crucial Role of High-Resolution Imagery</h3><p>Ultimately, the goal is to capture photographs (or video) in the highest quality possible, since it will directly impact the quality that the 3D model will be rendered in. Images with high pixel count ensure clarity and sharpness in the image capture, which will result in the creation of higher quality 3D models, so you’ll want to select video and image footage that is high resolution and clear to capture the finer details and ensure accuracy.</p><h3>Exploring Various Angles for Detailed Representation</h3><p>When capturing images for photogrammetry to achieve a detailed representation, it's necessary to explore various angles and viewpoints of the object or scene. To achieve a detailed representation of an object, you’ll want to cover a wide range of perspectives. A detailed representation necessitates covering an array of perspectives, including but not limited to:</p><ul><li><strong>Top-Down View:</strong> This perspective offers a unique vantage point, capturing the subject from above, revealing its intricate details.</li><li><strong>Front-Facing View:</strong> A straightforward view that presents the subject in its entirety, focusing on its frontal features.</li><li><strong>360-Degree Rotation:</strong> Circling the subject from all angles ensures that no facet is left unexamined, yielding a comprehensive view.</li><li><strong>Close-Up Shots:</strong> Zooming in to capture intricate nuances and fine details that may otherwise be missed.</li><li><strong>Diagonal Views:</strong> Offering a dynamic angle, diagonal viewpoints can accentuate the subject's shape and characteristics.</li><li><strong>Varying Heights:</strong> Experimenting with different heights allows you to capture your subject from various elevations, adding depth to the representation.</li></ul><p><img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1708454070526-1708454070526.png" alt="ROV Various Angles for Detailed Representation" class="fr-fic fr-dii"></p><p>Remember, it's not just about capturing these perspectives in isolation; it's equally important to ensure substantial image overlap (50% or more) between consecutive photos. This overlap is the linchpin of the final 3D model's quality, ensuring that no detail is left uncovered and that your model emerges with the utmost precision and accuracy.</p><h3>How Does Proper Lighting Improve Quality of the Model</h3><p>The quality of your photogrammetry model is significantly impacted by the lighting conditions during image acquisition. Adequate illumination of the subject is key to reducing the chances of distortion. Achieving the right lighting involves controlling external light sources, using diffusers or reflectors to soften and evenly distribute light, and avoiding extreme contrasts. Consistency in lighting throughout the entire shoot is paramount, making overcast days a preferred choice for outdoor shooting.</p><h3>Factors to Consider When Choosing the Right Camera for Image Acquisition</h3><p>When choosing the right camera for image acquisition in photogrammetry requires careful consideration of several key components to ensure the best results. Factors to weigh include:</p><ul><li>Image resolution</li><li>Sensor size</li><li>Lens quality</li><li>Lens focal length</li><li>Manual controls</li></ul><p>Most importantly, you’ll want a camera with a high resolution sensor, and manual control over settings to capture the highest quality images. It is also essential to calibrate the camera to correct any lens distortion.</p><p>Some other features to consider include stability, image format, and time-lapse and interval shooting. Many cameras now come with built in image stabilization, which will aid in capturing crisp, highly detailed images, and most digital cameras also support common file formats such as jpeg, which is supported by most photogrammetry software. Time-lapse capabilities also simplify the process and ensure consistent image capture.</p><h3>Maximizing Precision in Reconstruction with Image Overlap</h3><p>To achieve accurate and detailed 3D models in photogrammetry, image overlap is a critical factor in the process. It is essential to capture a significant number of images with overlap for precise reconstruction. The overlap is useful for matching features and establishing correlations to allow the photogrammetry software to stitch the images together and create an accurate 3D model.</p><p>An overlap of anywhere from 50% up to 80% is generally recommended for best results of feature detection and matching, to improve the accuracy of the reconstruction. You’ll also want to keep in mind both side-to-side and back-to-front overlaps to help accurately align and triangulate features, and ensure optimal coverage of the subject from multiple angles. The more information you provide, the more accurate the reconstruction will be.</p><p>Varying camera orientations and multiple passes are also incredibly useful for providing additional coverage and overlap, leading to more precise reconstructions. Additionally, you’ll want to minimize occlusions or obstructions which can prevent accurate feature matching and hinder the reconstruction process. If occlusions are unavoidable, capturing additional images from different viewpoints or angles can help compensate for the missing information.</p></section><section><h2>Utilizing Deep Trekker ROVs for Photogrammetry</h2><p>Deep Trekker offers portable, intuitive, and affordable underwater drones, with enhanced 4K cameras, powerful LED floodlights, and unmatched stability, making them perfect for photogrammetry projects.</p></section><section><h3>Customer-Driven Innovation</h3><p>At Deep Trekker, we are dedicated to designing industry-leading ROVs that excel in diverse underwater tasks.
