I processed a flight with step 1, initial processing only, at 1/4 image size, so I could add GCPs. The point cloud looked normal, so I imported the GCPs and marked them all using the RayCloud editor, which all went fine as well. I know the elevations of the GCPs are correct as we fly this area very often. Then after re-processing step 1 with the GCPs, the point cloud became very misshapen, and bowed in the middle:
I checked all the GCPs and the error in elevation is tens to almost a hundred meters at the edges. Does anyone know what is causing this and how to fix it? Below is the quality report. Thanks!
