Research on Landslide Deformation Analysis Method from Terrestrial Laser Scanning
Abstract Theoretical precision of scanning points is analyzed and some key techniques, such as point cloud data acquisition and point cloud data preprocessing are discussed with an example of a landslide in Sichuan Lixian. Then a very intuitive and comprehensive landslide deformation analysis method is presented in this paper. Furthermore, a new method of extracting the geometric features of telegraph poles and tree trunks in the landslide area is presented in order to make the best of non-ground point cloud data.
Key words :
