Point cloud data slope model reconstruction process and method.

Processing steps	Handling operations	Approach
1	Point cloud data preprocessing	Noise point removal, invalid point cloud data filtering
2	Target localization and registration	It is based on the software’s target positioning and converting the station scan data to a unified coordinate system
3	Visual model building	We reconstruct the visualization model of the slope through the point cloud meshing algorithm
4	Point cloud simplification	Simplify the reconstructed model to make the analysis as easy as possible
5	Deformation measurement	The models in different periods are superimposed and analyzed through point cloud superposition to obtain deformation data
