基于点云数据的变电站三维仿真模型的实现及展望

Ｒealization and Prospect of 3d Simulation Model of Substation Based on Point Cloud Data

摘要:

使用 GPS、StreetView 全景相机、室内三维移动扫描仪 IMS3D、DPI － 8 手持式三维激光扫描仪的作业方法，获 取变电站室内室外设备、场景等的多角度实景照、片点云数据，进而对获取的数据进行分析处理。然后使用 Autodesk 3d Max 工具，对三维场景中的变电站设备、建筑及周边地形环境等按照给定的建模标准进行高精细建模。首先建立 设备模型库; 再结合真实地形绘制整个变电站三维模型; 最后获得与现场一致的三维模型。

Abstract:

Using GPS，StreetView panoramic camera，indoor 3d mobile scanner IMS3D and DPI － 8 hand － held 3d laser scanner，the multi － angle real imaging and a piece of point cloud data for indoor and outdoor substation equipment are obtained and processed． Then，using Autodesk 3d Max tool，the high and fine modeling of substation equipment，construction and surrounding terrain environment in 3d scene is carried out according to the given modeling standard． The equipment model library is established，and the 3d model of the whole substation is drawn with the real terrain． Finally，the three － dimensional model is obtained．
