This movie shows ROV Latis rehersing a mission from different viewpoints - from the ship, from the surface and under the water and from the vehicle itself. Using previously acquired terrain data the seabed is also simulated. The movie shows what the ROV pilot would be able to visualise using our new augmented reality tools as the ROV is launched from the ship, undertakes self-tuning and them embarks on its mission.
The instantaneous thruster power/direction, vehicle speed/direction and current strength/direction is depicted by green, red and blue indicators on the vehicle and is updated in real-time by an innovative navigation and positioning control system. Using geo-referenced positioning data from the vehicle and the ship together with linear and angular acceleration data from the on board inertial navigation system, this new control system determines the vehicle's position and motion relative to the ship and to the seabed and continuously re-calculates the optimal shaft speed of each of the thrusters to achieve the desired (or preprogrammed) speed, altitude, heading, attitude, vertical speed and yaw irrespective of the direction or strength of the current.
Demo of RIEGL Airborne Bathy Scanner in Camcopter UAV
It's not an AUV but a UAV. So an unmanned vehicle, but in the air instead of underwater. This movie shows a demonstration of the bathymetric laser scanning capabilities of the RIEGL VQ-820-GU hydrographic airborne sensor in reality. For more information on the technical side, please see the news release on Hydro International.
