Abstract

The objective of this work is to explore the feasibility and accuracy of using a fixed-wing unmanned aerial vehicle (UAV) to obtain slope surface information data. Herein, the precision of the slope model based on UAV images was evaluated using ground control points and the point cloud data obtained by a terrestrial laser scanner. The results show that the proposed model is accurate at the decimeter level. The proposed method is reliable and practical and can be used in similar projects to obtain high-precision surface data on slopes.
