I processed my imagery (~2000 images) with my GCPs input into Pix 4D, and I found myself getting pretty small Geolocation errors (x,y)(less than 5 cm RMS in the quality report), and the GCPs lining up really well with the the center of my visual targets shown on the interface for my processed 3d model. However, when I load my exported Pix4D-made orthomosaic and my GCPs into my ArcMap 10.4 for other processing, my ground targets that I can see in my orthomosaic are over half a meter away from my marked GCPs. What’s going on here? I feel like my entire orthomosaic shifted one direction about 0.7 meters, and now I can’t do the ArcMap processing that I needed with a reliable orthomosaic. I already made sure that everything was in the proper coordinate system and projection in both softwares, so that’s not the issue.
