三维激光扫描技术是国际上近期发展的一项高新技术。随着三维激光扫描仪在工程领域的广泛应用,这种技术已经引起了广大科研人员的关注。文中介绍了三维激光扫描测量仪的工作原理,给出了处理点云数据的过程和方法,阐述了建筑物三维建模的方法,并用实例介绍了整体方法的实现过程和效果。实践结果表明,利用三维激光扫描技术获取的空间点云数据,可快速建立结构复杂、不规则的场景的三维可视化模型,既省时又省力,这种能力是现行的三维建模软件所不可比拟的。

Three-dimensional laser scanning is a new high technology developed in recent years. With the wide application of the three-dimensional laser scanner in engineering, this technology has attracted the attention of many researchers. In this paper, the operation principle of a three-dimensional laser scanning measurement instrument is presented; the procedure and method for processing point cloud is given; the method for producing the three-dimensional model of a building is described; and the implementation and effectiveness of the method are demonstrated. The practical result shows that the space point cloud data obtained by this three-dimensional laser scanning technology can be used to establish the three-dimensional visual models for complex and irregular buildings quickly and easily. Its capability is not possessed in the current three-dimensional modeling softwares.
