摘要
提出了一种利用激光扫描仪采集的点云数据对建筑物进行快速三维重建的方案。对于待扫描的建筑物,获取从不同角度扫描的激光点云,首先进行相邻扫描站的激光点云自动拼接,生成统一的点云模型,然后再通过点云提取特征线,利用共面条件,提取建筑物框架生成三维模型,最后得出利用三维激光扫描技术可以快速建立三维空间的可视化模型,解决了传统测量仪器和测量方法在变电站等特殊领域的不足的问题。
This paper provides a scheme to construct architecture using laser scanner. In the approach, laser point cloud are scanned from different scan positions. The point cloud coming from neighbor scan stations are automatic registered to combine a uniform model and automatic joining. The method, using the condition of coplanarity, picks up data of the building and generates 3D model by means of 3D laser scanning tech to quickly build 3D visualization model. The experiment result shows that it will bring the application mode and technical advantage, which traditional mapping way cannot have.
