The operation mode of UAV equipped with LiDAR can significantly reduce the efficiency and cost of highway terrain acquisition. At present, due to the complicated terrain and weak signal of mountain road, it is difficult to collect terrain data. In view of the above problems, this paper puts forward the technology of BDS assisted terrain acquisition and processing on complex mountain roads. This paper describes in detail the new signal unfuzzy acquisition and tracking algorithm and multi-antenna positioning and attitude determination technology and equipment of BDS-3 mountain highway, through millimeter wave Lidar altimetry technology, imitation ground flight, air-ground multi-source data combined with air three-direction method and other technologies. To realize efficient 3D collection and 3D reconstruction of massive original images of terrain of complex mountain traffic lines in the range of 100 km. Finally, a case study of 100 km mountain road is taken to verify the effectiveness of the method.
配备激光雷达的无人机作业模式可显著降低公路地形采集的效率和成本。目前，由于山路地形复杂、信号微弱，地形数据采集困难。针对上述问题，本文提出了复杂山区道路北斗卫星导航系统（BDS）辅助地形采集与处理技术。本文详细介绍了BDS-3山区公路新的信号解模糊采集与跟踪算法以及多天线定位与姿态确定技术和设备，通过毫米波激光雷达测高术、模拟地面飞行、空-地多源数据结合空三方向法等技术，实现100公里范围内复杂山区交通线路地形海量原始图像的高效三维采集与三维重建。最后，以100公里山路为例进行案例研究，验证该方法的有效性。
