The LaserScope 3D Subsea Laser Scanning system developed by Ocean Physics is based on the principle of structured light 3D imaging, and can be used to scan seafloor topography or underwater structures at close range by using a tripod for bottom observation or an integrated ROV.
The system can acquire video images carrying 3D information of the target, pre-process the video images, and perform algorithms such as light bar extraction, processing and point cloud conversion to obtain 3D point cloud data of the target surface. At present, it has been applied to a number of users, and has completed the underwater field scanning of different landforms such as underwater flat sandy slope area, large carbonate crusted rocky area and flat sedimentation area.
Application:
