英文摘要：

On the basis of briefly introduction to the main modern deformation monitoring methods,this paper emphatically expounds the deformation monitoring method based on vehicle borne laser scanning system,based on the gray system theory,the landslide deformation monitoring model is derived by using points cloud data.The selection method of landslide monitoring points is discussed. The vehicle borne laser scanning system is used for landslide monitoring of a landslide area,the grey model method is used to analyze the data of monitoring points. The experimental results show that： using vehicle borne laser scanning system points cloud data in landslide monitoring is feasible.
