In recent years,three-dimensional laser scanning technology has been widely used in engineering tech-nology and has important applications in foundation pit monitoring projects.This article introduces the basic prin-ciple of 3D laser scanning and its operating methods in engineering applications,and elaborates on the principle of point cloud stitching and registration.At the same time,it introduces and compares various methods of point cloud model processing.Taking an actual project as an example,the dimensions of the foundation pit,deflection of the support rod,and other parameters were measured according to the steps of model acquisition,registration,noise re-duction,and model measurement,to verify the safety of engineering construction.
