3D laser scanning technology has become an important means of measurement for 3D model construction of buildings,and its 3D laser point cloud data is mainly obtained through the standing or handheld mobile 3D laser scanner.This paper briefly introduces the working principle of two 3D laser scanners and the data processing process of 3D laser point cloud,and expounds the construction method of building 3D laser scanning technology based on the project engineering example,and verifies the accuracy of some building corner points by analytical method.The results show that this method can meet the 3D model construction of buildings with large indoor space and complex scenes.
