摘要
机载激光雷达系统(Airborne LiDAR System)是一款高速度、高性能、长距离的航空测量设备,与传统摄影测量模式相比,LiDAR技术具有自动化程度高、生产周期短、成图精度高、费用低等优点。文章以黄河上游甘肃段为例,基于国产软件LiDAR点云数据处理系统LiDAR-DP、PixelCube数字摄影测量系统,介绍了利用机载Li-DAR数据快速实现DEM和DOM生产更新的技术流程和方法,并对成果精度进行了分析。
Airborne LiDAR system is a high-speed,high-performance and long-distance aerial measurement equipment.Compared with the traditional aerial measurement production mode,LiDAR measurement technology has the advantages of short production cy-cle,high mapping accuracy and low cost.Taking the upper reaches of the Yellow River Gansu section as an example,based on the domestic software LiDAR point cloud data processing system LiDAR DP and PixelCube digital photogrammetric system,this paper in-troduces the technical process and method of using airborne LiDAR data to quickly update DEM and DOM production,and analyzes the accuracy of the results.
