Abstract
Deformation analysis based on point cloud is one of the major applications in surveying engineering, which makes up for the shortcomings of traditional surveying methods that hardly reflect the overall variation with fewer sampling points. A deformation analysis method of roads in mining areas based on vehicle point cloud is proposed in our study, which consists of three parts: (1) fine registration of multitemporal point cloud; (2) accurate extraction of the ground and road's point cloud; (3) rapid detection of road's deformation information. To verify the feasibility of the proposed method, a road's point cloud in mining areas captured by the mobile laser scanner is selected. Results show that the method can extract the complete road deformation information and provide technical support for subsidence monitoring.
