摘要: 本文面向离岸海岛实景三维需求与技术挑战,以珠海市庙湾岛为观测对象,采用无人机倾斜摄影与激光扫描的方式进行离岸海岛的实景三维数据获取。详细介绍了无人机任务规划、地面控制与实景三维数据处理工作,以及基于无参数布料模拟滤波的DEM生成,最终通过检查点验证了数据的绝对精度。结果表明,获取的正射、倾斜影像总中误差分别为14.72、6.60cm;点云、DSM、DEM高程中误差分别为3.10、6.20、7.11cm,满足离岸海岛实景三维展示与调查管理的需求。

Abstract: This paper addresses the needs and technical challenges of real 3D for offshore islands, taking the Miaowan Island in Zhuhai, China as the observation object, using UAV oblique photogrammetry and laser scanning for real 3D data acquisition of offshore islands. Details of the UAV mission planning, ground control and live 3D data processing work, and DEM generation based on parameter-free cloth simulation filtering are presented. The absolute accuracy of the data is verified by checkpoints. The results show that the total mean square error of the acquired ortho-and oblique images are 14.72 and 6.60cm,respectively; the errors of the point cloud, DSM and DEM elevations are 3.10, 6.20 and 7.11cm,respectively, which meet the needs of offshore island live 3D display and survey management.

Key words: offshore islands, real 3D, unmanned aerial vehicles, photogrammetry, LiDAR, ground filtering
