What causes holes around control points and lost photos after aerotriangulation when adding GCPs? Is it because of innacurate control points, wrong accuracy or because of innacurate placement in too many or not enough photos? Control point are measured using GNSS with RTK.
Before using GCPs:
After using GCPs:
Report looks "excellent" with accuracy achieving <1cm which is too good to be true:
I got the same problem, How can I solve it?
Try to run aerotriangulation with all tangential, skew, aspect parameters enabled. Also don't use GCP which are on edge of photos. What camera you have?
We made cameras ourselves, it is AMC5150 which is intergrated by 5*phaseone 150Mp cameras
