Methods for cleaning and joining LiDAR and Sonar point clouds
My company surveys above and below water, and the current method for tying both datasets together involves laboriously deleting the lidar/photogrammetry pointcloud points off the surface of the water, then Kriging with the single beam sonar points to create the full model.
The cleaning process is painfully slow using Hypack, and I'd love to find another way of doing it. I've tinkered with using Multispectral imagery to isolate the water and turning it into a polygon mask, but results have been mixed. I'm now seeing whether I can use the point density and intensity of lidar data to remove the bad points, and hope to have better success
Are there other methods or programs that can do this for me?
