摘　　要：晋城矿区地形复杂,多位于山区和丘陵地带、地势起伏较大甚至包括悬崖和峭壁,传统地形测绘方法难以满足测量要求。三维激光扫描技术数字化、快速、非接触的特点正好可以解决这类问题。文中介绍了三维激光扫描技术的基本原理,并结合采集的矿山地形数据,进行了地形点云数据的采集方法、点云数据拼接方法、点云数据中植被信息剔除方法、DEM模型建立的相关研究。The terrain was complex,mostly located in the mountains and hills,the terrain was undulating and even includes cliffs and cliffs in Jincheng mining area, the traditional terrain mapping method was difficult to meet the measurement requirements. Characteristics of digital,fast,non-contact of three-dimensional laser scanning technology just could solve the problem. In this paper,the basic principle of 3D laser scanning technology was introduced,and combining the mine terrain data acquisition,the collection method of the terrain point cloud data,the splicing method of the point cloud data, the deletion method of the point cloud data in vegetation information,and the DEM model were carried out the related research.
