摘要
首先通过无人机智能采集线路走廊的高分辨率可见光影像;再对影像数据进行空三解算和点云加密;然后通过专业软件进行树障量测分析,以提高树障巡视的效率、安全性和准确度,保障电网运行安全;最后通过工程实践验证了该技术的可靠性。
In this paper,we collected the visible light images of overhead line by unmanned aerial vehicle intelligently,and made the aerial triangulation and densification for point clouds by photogrammetry software.And then,we used the professional software to measure and analyze the tree obstacle.Finally,we verified the reliability of the method by engineering practice.This study can improve the efficiency,safety and accuracy of tree obstacle measurement,and ensure the safety of power grid operation.
