机载LIDAR系统校准方案优化设计

摘要

To optimize the calibration scheme of airborne LIDAR (Light Detection and Ranging) system, this research aimed at analyzing and comparing the impacts on the calibration results of laser scanning datasets, which were caused by different test area, flying altitude and speed. Three test areas which are Tianjin, Yantai and Zhoashan were employed in the experiment. Besides, some other parameters are considered, such as pulse magnitude of laser scanner,scanning field of view, scanning frequency. In the end, an optimal LIDAR calibration scheme are offered.%为优化机载LIDAR(Light Detection and Ranging)系统校准方案,基于天津、烟台和舟山3个标准检校场的试验数据,分析比较不同检校场地、不同飞行航高和不同飞行航速对激光扫描数据检校结果的影响.探索激光扫描器脉冲能量大小、激光扫描仪视场角、扫描频率等参数设置对激光扫描数据检校结果的影响,最终提供了最优的激光扫描系统校准方案.
