Research on Surface Deformation Monitoring Based on the UAV Lidar
This article mainly explores the principles of the three traditional point cloud region settlement monitor-ing methods of M2M,C2M and P2P and their advantages and disadvantages,and elaborates on the principle and process of the vertical deformation monitoring algorithm that considers the optimal step size.It studies the influence of the grid step size and non-ground points on the vertical deformation monitoring accuracy of the three methods under different point cloud densities,compares and analyzes the point cloud monitoring accuracy of different meth-ods when the point cloud density is 5,and finally uses the vertical deformation monitoring algorithm that considers the optimal step size to calculate the vertical deformation of the mining area.
