摘要
文章介绍了三维激光扫描仪工作原理,给出了处理点云数据的过程和方法,阐述了地形场景建模的方法,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,可快速建立不规则场景的三维可视化模型,进而导入CAD软件来提取建筑物特征及其各种线划图。省时又省力,这种能力是传统测量方法所不能比拟的。
In this paper,the operation principle of a three-dimensional laser scanning measurement is presented;the procedure and method for processing point cloud is given;the method for producing the three-dimensional of a building is described;and the implementation and effectiveness of the method are demonstrated.The result shows that 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 software.And import to CAD software,what the people is familiar with,to extract buildings' various features and sectional view.Time-saving and convenient,this ability is not the traditional method for measuring can compare with.
