EXPERIMENTAL RESEARCH ON ACCURACY OF AEROTRIANGULATION FOR UAV IMAGERY

Abstract

In this paper, the experimental research utilized UAV imageries of two areas, assessed the accuracy of aerial triangulation on the basis of different photo-control points distributions using two kinds of software (Geolord-AT and PixelGrid). The experimental results show that the accuracy of aerotriangulation of UAV imagery can be satifactory to the accuracy of 1:500 scale topographic maps in the intensive control conditions. The experimental processing steps and results provide experience and reference for production.
