【摘要】：为快速、准确地同步采集陆地及水下三维点云,构建船载激光三维扫描系统,集成三维激光扫描仪、多波束测深仪和光纤罗经等设备,介绍系统组成及其工作原理,总结了系统的关键技术,应用于北江某河段三维一体化测量,获得了精细的陆地水下一体化点云模型,与常规测量进行对比并统计了数据精度。结果表明,船载激光三维扫描成果精度满足规范要求。
[Abstract]:In order to quickly and accurately collect 3D point clouds on land and underwater, build a 3D laser scanning system, integrate 3D laser scanner, multi-beam sounder and fiber optic compass, the paper introduces the composition and working principle of the system. The key technologies of the system are summarized and applied to the 3D integrated survey of a certain reach of the Beijiang River. A fine land- underwater integrated point cloud model is obtained, which is compared with the conventional survey and the accuracy of the data is calculated. The results show that the accuracy of 3D laser scanning can meet the requirements of the specification.
