三维激光扫描技术在排土场方量计算中的应用

Application of 3D Laser Scanning Technology in Calculating Amount of Waste-Dump

运用Riegl VZ-400三维激光扫描仪对排土场进行了扫描,并对扫描数据进行了去噪、拼接、坐标转换、格式转换的处理,将排土场的点云数据以及原始地形分别生成栅格数据,运用ArcGIS中填挖方的计算方法对排土场的方量进行了计算,得出排土场的现有方量为78.9×104m3,已经超出了其设计的65×104m3,存在安全隐患,需采用有效措施进行防范。

The 3D laser scanner, Riegl VZ -400, is applied in the calculating amount of waste-dump. All the scan data have been treated with denoising, splicing, coordinate transformation and format conversion. And the raster data are generated respectively through the point cloud data and original landform of waste - dump. Then the amount of waste - dump can be calculated by the excava- tion - and - filling method of ArcGIS. Results show that the present amount of waste - dump is about 0.789 million cubic meters and it has already exceeded the maximum capacity of design（0.65 million cubic meters）. It has disadvantages in security and some meas-ures should be taken to alleviate the problem.
