Application of 3D laser scanning technology in landslide disaster monitoring
Traditional landslide monitoring methods are inefficient and limited by field conditions.Three-dimensional laser scanning technology is a device that can quickly,accurately,and comprehensively obtain the three-dimensional spatial information of objects or scenes.It has the advantages of fast,comprehensive,efficient,and flexible,and can obtain the overall change information of the landslide surface.This article introduces the basic principles,workflow,and data processing methods of three-dimensional laser scanning technology,and applies it to the monitoring of a rock landslide in Aba Prefecture,Sichuan Province.By comparing it with the traditional total station monitoring method,the accuracy and feasibility of three-dimensional laser scanning technology for monitoring landslide deformation are verified.
