Research On The Extraction Method Of The Surface Reconstruction And Deformation Information Of Slope Point Cloud

Our country is a relatively special geographical environment,geological conditions are relatively complex country.China's geological disasters,landslides is one of the common.Slope deformation monitoring is one of the important means to prevent landslide hazard.With the.development of Surveying and mapping technology,3D laser scanning technology is applied to slope deformation monitoring more and more attention.This technology not only saves time and reduces labor intensity and has no contact with all the time measurement,but also can get the whole deformation information of slope after data extraction and modeling.The slope model reconstruction and deformation information extraction of point cloud data is the key technology of 3D laser scanning applied to slope deformation monitoring,and it has become a research hotspot.Aiming at the problem of the model reconstruction of the slope point cloud data,this paper adopts the improved RBF algorithm,and improves the efficiency and the precision of the RBF algorithm.In view of the problem of slope point cloud information extraction,the accuracy and efficiency of Cyclone combined with CAD were obtained by comparing the data precision and efficiency of the method.
