Underwater Photogrammetry: Mask by Depth
« on: July 20, 2020, 06:13:04 PM »
When using Metashape with underwater datasets, dense cloud noise is sometimes generated from source imagery from more distant photos. Water clarity can be a real issue with underwater photogrammetry, and a simple solution to the problem would be enabling a way to generate masks from depth maps. If after setting scale, you could set a distance threshold (say 4 meters), and areas where depth maps indicate that the camera is more than 4m from the surface to be reconstructed would be masked out. It seems like this wouldn't be too hard to implement and would enable significant improvements in underwater model clarity.
