地面三维激光扫描技术在变电站精细测量中的应用

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。

Application of Ground 3D Laser Scanning Technique in Substation Fine Measurement

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 threed-imensional modeling and visualization of transformer substation are realized.
