摘要
机载LIDAR系统是一种主动式对地观测系统,主要由IMU/DGPS系统、激光扫描测距系统和成像装置所组成。目前常用的扫描方式有:有线扫描、圆锥扫描和纤维光学阵列扫描等3种扫描方式。文中论述了机载LIDAR系统的原理和工作流程,并对目前的几种LIDAR系统、LIDAR系统与INSAR、摄影测量等做了分析和比较。对机载LIDAR系统的应用现状和前景进行了系统总结和展望。
Airborne LIDAR which consists of IMU/DGPS, LIDAR scanning and rang detecting system, and imaging equipment, is a kind of active earth-observation system. Now there are three scanning styles： linear scanning, taper scanning, and fibre optics array scanning etc. The principle and work flow of airborne LIDAR are discussed LIDAR, INSAR and Photogrammetry systems are analyzed and compared. Finally, the present situation and foreground application of airborne are summarized LIDAR system.
