| Abstract: | This paper aims to use small low-altitude aerial platform and the non-metric small format cameras, carry dynamic GNSS/INS integrated system to obtain the exposure station coordinates and attitude to replace the ground control points of the encryption, study the using of UAVs GNSS/INS assisted system to set the photogrammetric control point in different resolution or different baseline number and aerial triangulation encryption, and analyze the plane and elevation accuracy, finally achieve to use a small amount of ground control points for the mapping of large-scale topographic maps. |
