UAV Aerial Triangulation and Accuracy Analysis with Scarce Controls in Highway Topographic Mapping

doi:10.13474/j.cnki.11-2246.2017.0364

Abstract

Abstract: Against the UAV aerial photogrammetry ground control points problem, this paper introduces a UAV aerial triangulation method. The method is based on dynamic PPP, using a single GNSS receiver to obtain coordinates of the camera site. By highway project experiments, it analyses the control point layout method and the accuracy of adjustment with scarce ground control points. The proposed method greatly reduces the effort of field work, simplifies the workflow of UAV aerial photography.

Key words: UAV, aerial triangulation, kinematic PPP, aerial photography, highway topographic map
