VBS RTK GPS-Assisted Self-Calibration Bundle Adjustment for Aerial Triangulation of Fixed-Wing Uas Images for Updating Topographic Maps

Abstract: Abstract:Unmanned Aircraft Systems (UASs) can collect high resolution and high quality images for local mapping. If the highly accurate GPS flying trajectory of a UAS is collected, it can support bundle adjustment aerial triangulation (AT) of UAS images and reduce the demands on ground control points (GCPs). This study installs a Trimble BD970 GNSS OEM on a fixed-wing UAS for capturing highly accurate GPS data by using a Virtual Base Station (VBS) RTK GPS technique for AT. Meanwhile, the GPS antenna-camera off… Show more

“…[14] tiny aerial fixed-wing aircraft for specific corridors. [15] a VBS RTK GPS aided self-calibration package adjustment was evaluated for aerial triangulation of UAV images to update 1:5000 topographic maps; collected data by flying a fixed-wing UAS equipped with a 550 m Canon EOS 5D Mark II camera of 24 mm focal length. The Root Mean Square Error (RMSE) was 0.27 m in planimetry and 0.24 m in height accuracy.…”
