三维激光扫描技术在建筑物建模上的应用

The Application of 3D Laser Scanning Technology on the Building's Modeling

三维激光扫描技术的应用领域日益广泛,但点云数据内业处理较为复杂,对此方面的研究一直是许多相关专业的热点.通过三维激光扫描仪对历史建筑进行扫描,对采集的数据进行处理,建立建筑物的三维模型.提出了控制网的布设方案,完成激光扫描仪坐标下点云数据向全站仪坐标下数据的转换,对海量点云数据去噪、拟合、建模,完整地建立建筑物的真三维模型,为建筑物的保护和管理提供了基础数据.

The application areas of 3D laser scanning technology become more and more widespread, but it is still complex for the indoor processing of point cloud, which is the hot research in lots of relevant specialties. The article points out the scan of historical buildings by 3D laser scanner, the processing of collected data, the 3D model of buildings, and the layout of control network. The point cloud under the laser scanner coordinate is converted into the data under the total station coordinate. A true 3D model is completely built through de-noising, fitting, and modeling of massive point cloud to provide the basic data for the protection and management of buildings in the future.
