Comparison of Three Camera Calibrations Based on UAV Images

The paper compares three on-site camera calibrations based on the same test area consisting of evenly distributed control points on a slightly moderated terrain having a size of 200x200 m area. The images were taken with three different UAVs and all camera calibrations were calculated with the same software. The goal of the comparative study was to determine the maximum accuracy that could be achieved for the same test area under slightly different conditions.
