[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.
