Research on the Application of Airborne Lidar Measurement Technology in Reservoir Engineering
Taking the application of airborne lidar measurement technology in Ziqiang Reservoir Project in Zhenba County of Shaanxi Province as an example,the equipment selection,route design,parameter setting,aerial triangulation calculation,point cloud filtering,image and point cloud fusion registration and three-dimensional modeling are discussed.The feasibility of the method is verified by accuracy inspection.The results show that the airborne lidar measurement technology can quickly and accurately obtain the DEM,DOM,DLG and three-dimensional model of the water conservancy project,which can provide reliable and multivariate basic terrain data for the design of the reservoir project.
