摘要: 变电站是重要的电力设施,对其进行测绘采集是三维建模与可视化、运行维护、管理、异常监控等工作的基础,但其中构筑物具有复杂、结构异形等特点。本文利用三维激光扫描技术获取点云数据,对变电站进行精细测量。提出了基于空间区域复杂度的划分(如将测区划分为均匀分布区、紧密排列区、气体绝缘封闭组合电器(GIS)区、过渡区)方法,并以新疆亚中变电站为例展示了该方法的应用,最终实现了变电站的三维建模与可视化。

Abstract: Transformer substation is an important electric power facility.Surveying and mapping is the foundation of three-dimensional modeling and visualization,operating maintenance,management and exception monitoring,but the structures are complex with structural heteromorphism.This paper adopts three-dimensional laser scanning technique to obtain point cloud data,making accurate measurement of transformer substation.It proposes a method based on the division of space region complexity (for example,dividing testing zone into uniform distribution region,close-packed array region,GIS region,transition region).Xinjiang Yazhong transformer substation is taken as an example to display the application of this method.At last,the three-dimensional modeling and visualization of transformer substation are realized.

Key words: 3D laser scanning technology, point cloud data, 3D modeling visualization, fine measurement
