Yes, you must be right. The only problem is that it takes days for alignment and that's why I have chosen the lowest setup. I'll redo it again and wait for a week and see the results. Do you have any suggestions for the alignment setup?
Since I have estimated coordinates for my cameras that are somewhat good, what do you think about including those coordinates in the alignment process? The first alignment was done without camera coordinates, just GCP's.
