浅谈机载LiDAR数据特点及处理方法

摘要

对各类遥感数据进行解译与建模,为最终用户提供有用的表达与格式一直都是摄影测量领域的重要研究课题.近年来,随着传感技术的发展,基于激光扫描仪、全球定位系统和惯性导航系统集成的机载LiDAR系统由于能够快速、准确地获取激光所达到地面及地面上对象表面的信息,因而已成为人们快速获取高精度、大规模3D地貌信息的重要工具.对LiDAR数据的解译与建模也成为热门的研究课题之一.%Interpretation and modeling of various remote sensing data has always been the hot topic in the area of photogrammetry.With the development of remote sensing technology,airborne LiDAR has become the important tool for high accuracy of 3D ground feature information based on the integration of laser scanning and global positioning.Therefore the intepretation and modeling of LiDAR has become the hot topic.
