摘要 低空旋翼无人机载LiDAR系统通过无人机平台集成三维激光扫描仪、定位定姿系统(Postitioning and Orientation System,POS)为快速获取海岛、海岸带等测区地理信息提供了一种新的解决方案。首先比较了旋翼无人机LiDAR系统与传统机载LiDAR系统的不同之处,然后在海岛测绘实例中分别使用中海达ARS-100机载LiDAR系统和华测AS-300H机载LiDAR系统进行了同一海岛地形测绘,期间使用GNSSRTK技术采集地面特征点三维坐标作为校核点,检验了两种国产旋翼无人机载LiDAR测量系统在海岛测绘中的定位精度,实验结果表明两种国产设备绝对精度均达到±10cm以内,验证了旋翼无人机载LiDAR技术在海岛礁测绘中的可行性。 The low-altitude rotor UAV-based LiDAR system integrates three-dimensional laser scanner and positioning and orientation system(POS)on the UAV platform,which provides a new solution for fast acquisition of geographic information of island and coastal zone.Firstly,the difference is compared between the rotor UAV LiDAR system and the traditional airborne LiDAR system.Then,in the case of island surveying,the HD ARS-100 airborne LiDAR system and the CHCNAV AS-300H airborne LiDAR system are used to carry out the same island topographic surveying,and the GNSS RTK technology is used to collect the three-dimensional coordinates of the ground feature points.The positioning accuracy of the two domestic rotor UAV-based LiDAR measuring systems in island surveying is tested.The experimental results show that the absolute accuracy of the two domestic equipments is within<10 cm.The feasibility of the Rotor UAV-based LiDAR technology in island reef surveying is verified.
