Low cost real time UAV stereo photogrammetry modelling technique – accuracy considerations

摘要

The paper presents accuracy considerations regarding three 3D modelling techniques. The tested new consumer type stereo camera (ZED 3D Stereolabs) has been implemented info an aerial mapping system, on board micro air vehicle MAV) and tested object has been mapped using a real-time photogrammetry with original real-time software application. The evaluated results has been compared with model gained with a state of art unmanned aerial vehicles (UAV) photogrammetry process using commercial UAV and commercial software, and the terrestrial photogrammetry modelling process with other commercial software. Papers concludes the tested real-time technology accuracy with compare to the traditional technique, and discusses real-time photogrammetry modelling in terms of engineering applications.
