Flash back on a demonstration performed by IVM staff with EDF One River One Territory a few days ago.
Survey and 3D reconstruction test in very low visibility and dense turbidity waters of a dam located in the French Alps.
While the ROV camera was able to see at maximum 15cm (!!), IVM solution was still able to record proper data up to 65cm from the subject.
Survey performed on a very small ROV, as with the BlueROV2 here. A good example of the HYDRO 300 good integrability.
