Photogrammetric performance of an ultralightweight Swinglet UAV

This paper is the first one to systematically compare results obtained with a swinglet CAM + Postflight Service powered by Pix4D to those obtained with a professional LIDAR carried onboard a manned helicopter. The main conclusion is that the accuracy of the Digital Terrain Model (DTM) based on swinglet CAM images taken at 150m height is in the range of 10-15cm.
