多旋翼单镜头无人机不同航线规划的三维建模方法评述

选用多旋翼单镜头无人机作为航摄设备，对同一建筑物规划交叉航线、全航线及5架次模拟航线，构建该建筑物的实景三维模型，并从模型完整性和地面控制点点位精度两个方面对3种不同航线三维建模方法进行评述。结果表明：①交叉航线建模方法控制点点位精度高，但模型完整性差；②全航线建模方法控制点点位精度高，模型完整性较高；③5架次模拟航线建模方法控制点点位精度略低，模型完整性最好。

A review of 3D modeling methods for different route planning of multi-rotor single-lens UAVs

The multi-rotor single-lens UAV as the aerial photography equipment is taken to plan three route for the same building, such as “cross-route”, “full route” and “5 times simulation routes”. The UAV operation efficiency, model integrity and ground control point accuracy are reviewed. The experimental results show that: ① The control point has high precision based on the “cross-route”, but the model integrity is poor; ② The precision of control points based on the “full-route” is high, and the model integrity is high; ③ The control point has a slightly lower precision based on “5 times simulation routes” and the model has the best integrity.
