CHASING Environmental: M2 PRO MAX Advanced with Grabber Arm 2

Photogrammetric 3D model of sunken aircraft wreck in Greece

ΒΜ Consulting Marine has dealt with underwater photogrammetry since early 2021 for the specific tasks, such as modeling underwater structures, wrecks and vessel hulls. They used up to now larger observation ROVs and high-end photogrammetric cameras which are expensive, precalibrated. Tehy recently started implementing CHASING M2 PRO MAX underwater robot in order to become more efficient and provide cost-effective solutions to their clients.

Why do we need underwater Photogrammetry?

Underwater photogrammetry is an emerging field extends the scope of photogrammetry applications from air and land to underwater environments. This method can create accurate 3D models or 2D maps of large underwater areas to record and analyze ships, aircraft wrecks, bridge piers, historical sites, etc., providing significant value for industries such as environmental monitoring, infrastructure inspection, and archaeology.

Challenges in Underwater Photogrammetry:

1. Lighting and visibility
2. Depth and temperature
3. Accuracy and scaling

Work Flow of Photogrammetric 3D model of sunken aircraft wreck:

1. ROV dive into sunken aircraft sea

CHASING M2 PRO MAX initiate 4K/30fps UHD video recording.

2. ROV Panoramic HD shooting

3. Complete recording, retrieve ROV

Retrieve reference card by CHASING Grabber Arm 2.

4. Process UHD photos with powerful photogrammetric software

Mesh model consists 15,925,892 faces and Cloud point model consists of more than 1.6 million points.

Client Values:

1.Increased safety & enhanced accessibility

CHASING M2 PRO MAX can dive to a maximum depth of 200 meters and feature an 8-propeller vector layout for 360-degree movement. Compared to divers, the ROV can explore more dangerous and inaccessible areas, significantly enhancing project safety.

2.Improved Efficiency and Cost Reduction

CHASING M2 PRO MAX comes standard with a 300W battery and can connect to a shore-based power supply for all-day operation. Using this underwater robot for photogrammetric image collection is an economical and efficient solution.

3.High-Quality Data Collection

CHASING M2 PRO MAX is equipped with an EIS anti-shake camera capable of capturing 4K/30fps high-definition video and 12-million-pixel static photos. Its external LED lights provide up to 8000 lumens of adjustable lighting, effectively reducing visual interference from particulate matter in the water. The stable underwater posture of the CHASING M2 PRO MAX allows for systematic, repeatable data collection.

4.Multi-Device Integration

CHASING M2 PRO MAX features a built-in docking station that allows for quick installation and removal of up to 5 accessories. It supports auxiliary camera for secondary imaging, LiDAR scanner for point cloud data collection, and a grabber arm for collecting underwater samples, enhancing operational efficiency with multidimensional data collection.

5.Real-Time Data Transmission

CHASING M2 PRO MAX can transmit data in real time to surface operators, allowing for immediate assessment and adjustments based on real-time feedback.

6.Archaeology and Cultural Heritage Preservation

Underwater photogrammetry enables archaeologists to document and study submerged artifacts like shipwrecks and aircraft without disturbing the site, preserving them for future generations. This non-invasive method uses high-tech to explore and reconstruct submerged ancient cultural heritage, offering new perspectives for historical research.

From the depths of innovation comes the CHASING M2 PRO MAX Underwater ROV Advanced Set, equipped with a 656-foot tether, designed to meet the rigorous demands of government and enterprise users. This industrial-grade ROV is engineered with cutting-edge technology, offering a new generation of accessory mounting, quick assembly and disassembly, and an advanced floodlight design. These features ensure a user-friendly, professional, and reliable underwater exploration experience.

Experience unparalleled 360-degree omni-directional movements and explore depths of up to 200 meters with ease. The CHASING M2 PRO MAX boasts a robust battery life of over 4 hours, allowing for extended underwater missions. Its integrated design includes five accessory ports, supporting more than 20 types of accessories, both from CHASING and third-party developers, enabling the simultaneous mounting of up to five accessories.

The innovative slide-in accessory assembly and disassembly technology streamlines the process, saving time and effort, making it convenient for users to adapt the ROV to various tasks swiftly. The external 8,000-lumen LED floodlights, featuring a dual light source with a 150-degree optimal beam angle, can be flexibly adjusted to eliminate visual interference from plankton reflections. The stepless brightness adjustment from 0-100% ensures every underwater detail is illuminated.

Equipped with the second-generation anti-stuck motor (C-MOTOR 2.0), the ROV delivers 30% more power and enhanced reliability, making it easy to clean and maintain.
