摘　　要：机载LIDAR(Light Detection and Ranging)是一种无需任何或仅需少量的地面控制点的安装在飞机上的激光探测和测距系统,用于获得高精度、高密度的三维坐标数据,并构建目标物的三维立体模型。LIDAR具有自动化程度高、受天气影响小、数据生产周期短等特点,为获取高分辨率地球空间信息,可提供一种全新的技术手段。简单介绍机载LIDAR系统组成、特点、发展现状和趋势,详细阐述LIDAR数据处理的过程,并对现在存在的问题进行简单的论述,总结其应用领域,并对未来进行展望。LIDAR（Light Detection and Ranging）, which is installed on the plane, is a kind of airborne laser detection and ranging system with little or even without ground control points. It can be used to obtain 3D coordinates with high precision and density and also to build 3D stereo models. LIDAR has the characteristics with high automation, with being less influenced by weather and with short period of processing data. In this paper, the LIDAR data process is explained elaborately and also its application and prospects are summarized.
