摘要
高海拔山区地形复杂、高差巨大、植被茂密、地形破碎,传统的无人机摄影测量很难保证精度,尤其是高程方向,无法满足工程要求,因此宜采用激光探测及测距技术,利用无人机变高飞行功能获取海量点云数据,进行地形图绘制。本文以飞马V10-LiDAR10长测程激光雷达为例,通过在西藏左贡峡谷地区的地形测量,利用检查点对点云的精度进行分析,验证了国产激光雷达能够满足1∶2000地形图测量生产需求,在复杂恶劣的地形环境中具有良好的适应性。
Aimed at high altitude complex terrain,dense vegetation,the traditional drone photogrammetry is difficult to ensure the accuracy.Especially the elevation direction,unable to meet the engineering requirements,so LiDAR is appropriate,using function of UAV of changeable fly to obtain amounts of point cloud data that draw topographic map.This paper takes the FeiMa V10-LiDAR10 long-range LiDAR for an example.Through the topographic survey in the Zuogong Canyon area of Tibet,the accuracy of point clouds is analyzed by using checkpoints,which is verified that the domestic LiDAR can meet the production requirements of 1∶2000 topographic map survey and has good adaptability in the complex and harsh terrain environment.
