摘要
面向变电站管理工作中对三维场景模型的实际需求,构建了基于三维激光扫描采集的海量点云数据的三维全真模型。首先运用激光扫描仪对变电站进行高精度测量,获得海量的离散点云数据,然后重点研究了基于海量点云数据预处理及自动曲面重建方法,实现了点云数据的自动遍历,快速重建出几何和拓扑真实的变电站三维模型,直观展示变电站场景真实的三维空间信息。
3D realistic modeling of transformer station uses massive point cloud by laser scanning. First, massive scattered point cloud was obtained using high resolution laser scanning of a transformer station. Subsequently,preprocess massive scattered point cloud and surface reconstruction were studied. Through massive point cloud transversal, geometrically/topologically realistic 3D model of a transformer station was reconstructed.
