摘　　要：地面三维激光扫描技术可以快速地采集目标物表面海量点云数据,利用点云能够准确重建空间三维模型。本文基于完全不同形状的两组点云数据,分别采用三角网格法和提取特征线法两种不同建模方法进行实验,完成模型重建,取得较好的效果。同时探讨了点云处理和模型重建的关键问题,为工程生产提供借鉴。Terrestrial 3D laser scanning technology can rapidly collect the surface point cloud data of objects, and accurately rebuild the three - dimensional space model. This article is based on two groups of completely different shapes point cloud data, using triangle mesh method and the characteristic line extracted method for experiments, completed the model reconstruction, and achieved good effect. At the same time the paper discusses the key problems of point cloud processing and model reconstruction, it will provide refer- ence for engineering production.
