一种适合于输电线路设计的激光点云分类与质检的方法

Exploring the Method of Laser Point Cloud Classification Design and Quality Inspection for Transmission Lines

随着激光雷达在输电线路的广泛应用,点云分类数据不断增多,但在输电线路电力设计中,却缺乏完善的点云分类设计与质检方法。为此,在总结输电线路电力设计特点的基础上,阐述激光雷达点云分类设计的内容与要求,提出在与地物类别相适宜的显示模式下,通过多视角、正射和立体的方式可视化检查点云分类质量的方法。通过某输电线路工程为例,运用该方案处理点云,结果表明本文方案归纳的点云分类内容合理全面、质检效果准确显著,可以很好地服务于电力优化设计选线。同时,也能为激光雷达在其他领域上的应用提供参考。

With the widespread application of LiDAR in transmission lines,point cloud classification data continues to increase.However,in the design of power transmission lines,there is a lack of comprehensive point cloud classification design and quality inspection methods.Therefore,on the basis of summarizing the characteristics of power transmission line design,this article elaborates on the content and requirements of LiDAR point cloud classification design in detail,and proposes a method of visually inspecting the quality of point cloud classification through multiple perspectives,orthography,and stereoscopic methods in a display mode suitable for ground object categories.Taking a certain transmission line project as an example,this scheme is applied to handle point clouds.The results show that the point cloud classification content summarized in this scheme is reasonable and comprehensive,and the quality inspection effect is accurate and significant,which can effectively serve the power optimization design and line selection.At the same time,it can also provide reference for the application of LiDAR in other fields.
