摘要
结合无人机航摄技术和三维激光扫描技术的优势,对硬件系统总体架构和软件系统主要功能模块进行分析,采用合理的数据编辑和滤波算法,形成了一套无人机空中激光扫描测绘系统。并在西安未央湖附近进行了实地飞行试验,对系统硬件的稳定性和软件各功能模块进行了测试,最后对采集的点云数据处理后的线划图精度进行了分析。分析得出该系统采集的点云数据滤波后内插生成的地形图主要指标达到了1∶500地形图的技术要求。
This paper combined the advantage of UAV aerial technology and 3 D laser scanning technology, analyzed the main function of the architecture of hardware system and software system module, used a kind of reasonable data editing and filtering algorithm, formed a set of UAV airborne laser scanning and mapping system;A field test flight conducted in the vicinity of Xi＇an Weiyang Lake, tested the stability of the system hardware and each function module of the system software, at last, analyzed the precision of DLG by data processing. Experiment shows the main indicators of topographic map through the system processing can meet the technological requirements of 1 ： 500 topographic map.
