以旋翼无人机倾斜摄影测量系统为基础，建立高分辨率、高精度三维实景模型，

Based on the tilting photogrammetry system of the rotary-wing UAV, a high-resolution and high-precision 3D real scene model was established, and the digital mapping production research was conducted. The results show that the geometric accuracy of the 3D solid model with real geographic coordinates and production based on this model The DLG's geometric accuracy (plane and elevation) meets the 1: 500 terrain surveying and mapping accuracy requirements.
