The project I am working on has a no photography policy so I probably shouldn’t send the data to external parties, but I did grab a screenshot of the mesh (point cloud is similar) to illustrate what artefacts I mean.
These artefacts are quite common around sharp edges in my experience so I would be surprised if you are not already familiar with the issue.
Not sure why this happens, there is nothing physically there so it must be some limitation with the point cloud algorithm. The point cloud is usually very good at organic shapes, not so much with smaller details and edges.
Another bug near edges happen in orthofotos near sharp edges and especially overhanging structures of roofs where it tries to use the dsm for surfaces in both elevations and fails at both.
Maybe some edge detection algorithm to make lines sharper ?
