摘　　要：在数字城市建设中,作者提出了利用三维激光扫描获取的数据进行建筑物模型构建的方法.在详细介绍三维激光扫描基本原理和总结建筑物几何建模方法的基础上,重点研究了三维激光扫描数据处理方法以及利用三维激光扫描数据进行建筑物特征点提取的方法和过程.对利用三维激光扫描数据进行建筑物模型构建工作中应注意的问题进行了说明.最后,作者利用一组三维激光扫描数据构建了一幢建筑物的几何模型,这为三维激光扫描在数字城市建设中的应用做了有益的探索.In digital city construction, the method of using 3D laser scan data to model is put forward. After detailed introducing the basic principle of3D laser scan and the methods of construction modeling, the dataprocessing of 3D laser scan has been emphatic studied, then the methods and process of abstracting key points of construction from 3D laser scan data have been studied too. And some noticed issues during construction modeling based on 3D laser scan have been illustrated. Finally, a construction modeling has been realized based on a group of 3D laser scan data, which will offer a good direction for application of 3D laser scan in the course of digital city construction.
