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.
