Establishment of High Precision Terrain Model of Eroded Gully with UAV Oblique Aerial Photos

[摘要] Taking the example of aerial modeling of erosion gullies in Shenmu county of northern Shaanxi in China, with oblique aerial photos acquired by a COTS (commercial off-the-shelf) UAV (unmanned aerial vehicle) (DJI INSPIRE-1) and 30 high-precision pre-deployed ground control points (GCPs) measured by FIFO A30 RTK (real-time kinematic). Establish the high-resolution measured 3D terrain model with the aid of high-precision ground control points, the efficiency of airphoto and modeling is relatively high, it indicates that eroded gully modeling and monitoring relying on UAV has good application prospect.
