Abstract: The basic principle and key technique of 3D laser scanning are described.The landslide monitoring data were obtained by using the three-dimensional laser scanning technology.Technical means such as deep image segmentation, point cloud data matching and point cloud filtering were adopted in the relative and absolute positioning and splicing of single station scanning data.The landslide DEM model was finally established, which is a beneficial trial in 3D monitoring and alarming of landslide.

Key words: Three-dimensional laser scanning, DEM, Model, Finite element modeling
