基于3维激光扫描技术建筑物建模研究

Study on building modeling based on 3-D laser scanning technology

为了研究建筑物点云数据最佳的3维建模方法,采用3维激光扫描仪获取建筑物点云数据,并进行了一定的预处理;采用3种方法进行建筑物建模,并对这3种建模方法进行了理论分析和实验验证。通过建模效果和复杂度对比分析,发现SketchUp软件建立的模型效果更佳。结果表明,建筑物点云数据用专业建模软件SketchUp建模比扫描仪系统软件CYCLONE和AutoCAD软件建模效果更好。

In order to study the best 3-D modeling method of the building point cloud data , the point cloud data of a building were acquired with a 3-D laser scanner and pretreated .Three methods were used for the modeling of the buildings . From the view of modeling effect and complexity , the model effect with the SketchUp software was the best .The results show that the modeling effect of the point cloud data of buildings with SketchUp software is better than those with the scanner system software CYCLONE and AutoCAD software .
