摘要/Abstract

摘要： 激光雷达已被广泛应用于高压/超高压输电线路的设计施工、数字化管理以及线路的安全巡检等方面，其中电力巡线软件的可视化管理是激光雷达巡检业务化应用的重要内容。提出基于B/S架构的激光雷达电力巡线可视化管理与分析系统的总体设计方案；基于WebGL等开发了输电走廊点云数据可视化管理与分析系统，采用改进的可修改的嵌套八叉树存储和索引点云数据，以及多细节层次等多模式渲染点云，实现输电线路三维场景交互、电力要素数据高效管理与调度、点云属性编辑与三维量测、剪裁、生成剖面图等实用工具与数据分析功能。实验结果表明激光雷达电力巡线软件在Web端的高效和可行性，应用前景广阔。

Abstract: LiDAR, being an active remote sensing technology, can obtain 3D information of surface feature and has extensive applications in power line fields, such as construction line selection, digital management, safety inspection, etc. However, the software visualized management ability is a serious limitation of its widespread use. In this paper, we built the overall and functional design of a LiDAR data visualized management and analysis system based on B/S architecture, focusing on electric power line inspection application requirements. WebGL was applied to develop this system and points cloud data were stored and indexed by an improved modifiable nested octree, and rendered by Levels of Detail and other technologies. A lot of practical function and tools, such as interaction in 3D scene, managing data of power line features, editing point cloud attribute, 3D measurement, clipping, profile map and points cloud filtering were all achieved. The research results show that LiDAR electric power line inspection in web browser is applicable and effective, and has prospective application in future.
