UAV elevation route planning and modeling analysis for complex mountain landslides in Dongchuan

Using single-lens four-rotor small UAV as experimental equipment, for single and high-drop landslides in complex mountain areas, the use of landslide-oriented elevation route planning is proposed in this paper, combined with traditional single-level routes and cross-cutting route planning to construct three-dimensional under different routes model. The methods of constructing three-dimensional (3D) models under different routes are evaluated and analyzed through three aspects: the degree of overlap, the integrity of the 3D model, and the accuracy of the 3D model analysis by placing ground targets. Experiments show that the use of elevation routes can achieve 98.72% heading overlap and 88.82% sideways overlap; the model texture details, color information and ground information richness obtained by using elevation routes are all better than that of the traditional two routes obtained; for target measurement error calculation, the accuracy of the model obtained by using the elevation route is higher.
