摘要
机载激光雷达测量技术是当代航空、航天遥感最具代表性之一的高新测绘技术,它集全球定位、惯性导航、激光测距等高新技术于一体,工作效率、数据精度高,能迅速获取地理空间物体的三维信息数据,一定程度上解决了传统航空、航天摄影测量获取地面三维信息不便的难题,机载激光雷达测量技术实际上已经代表了对地观测领域一个新的技术发展方向。本文重点探讨机载激光雷达点云数据制作DEM的关键生产技术流程,以及在生产过程中的机载激光雷达点云数据常见问题处理方法。
Airborne LiDAR measurement technology is one of the most representative high-tech surveying and mapping technologies in modern airborne and spaceborne remote sensing.It integrates high-tech technologies such as global positioning,inertial navigation,laser ranging,etc.It has fast work efficiency and high data accuracy,and can quickly obtain 3D information data of geospatial ob-jects.To some extent,it solves the problem of inconvenient acquisition of 3D information on the ground by traditional aerial and aero-space photogrammetry.In fact,the airborne LiDAR measurement technology has already represented a new technical development di-rection in the field of earth observation.This paper focuses on the key process of DEM production from airborne LiDAR point cloud da-ta,and the processing methods of common problems in the production process.
