摘要
无人机机载LiDAR是集全球导航系统、DGPS/IMU惯导系统和激光雷达系统于一身的综合航测平台.为了研究对比无人机机载LiDAR技术和传统低空摄影测量技术的优越性、创新技术应用手段,将LiDAR技术与无人机技术相结合,利用机载LiDAR外业采集的测区海量LiDAR点云数据,进行点云解算、点云分类和渲染等内业数据处理技术,并提取高程信息和点云纹理信息,完成测区三维模型建设,最后根据行业标准和测量规范《数字航空摄影测量》验证测量精度.结果表明,机载LiDAR采集的点云精度可以满足生产精度要求.无人机机载LiDAR的技术应用将有效提高无人机航测的精度和效率,满足更多复杂航测场景应用.
Abstract
Airborne LiDAR is an integrated aerial survey platform that integrates global navigation system,DGPS/IMU inertial navigation system and LiDAR system.In order to study and compare the superiority of airborne LiDAR technology and traditional low-altitude photography and measurement technology,innovative technology application means are combined with LiDAR technology and massive LiDAR point cloud data collected by airborne LiDAR field industry are carried out such internal data processing technologies as point cloud solution,point cloud classification and rendering.The elevation information and point cloud texture information were extracted to complete the 3D model construction of the measurement area.Finally,the measurement accuracy was verified according to the industry standard and measurement specification Digital Aerial Photogrammetry.The data results showed that the point cloud accuracy collected by airborne LiDAR could meet the production accuracy requirements.The application of airborne LiDAR technology in UAV will effectively improve the accuracy and efficiency of UAV aerial survey,and meet the needs of more complex aerial survey scenarios.
