摘要
电力走廊测量是电力线安全巡检的重要内容,激光雷达技术与影像技术成为近年来电力线巡检研究的热点。采用机载激光雷达点云和摄像机影像融合的方法进行电力走廊实时测量研究。首先,获取同一区域的两种数据,根据两种数据同名点共线关系,建立三维点云与二维影像间的映射;然后,对无影像点进行三维坐标赋值;最后,以融合后的数据为基准,进行电力走廊的实时监测。实验结果表明本文的方案与传统方法相比,精度可满足量测要求,效率比传统方式更高,能满足电力线应急巡检需求。
Power corridor measurement is an important part of power line safety inspection,and lidar technology and imaging technology have become hot spots in power line inspection research in recent years.Firstly,two kinds of data in the same area were obtained.According to the collinear relationship of the two data points with the same name,the mapping between the 3D point cloud and the 2D image was established.Then,3D coordinate assignments were made to the imageless points.Finally,real-time monitoring of the power corridor was carried out based on the fused data.The experimental results show that compared with the traditional method,the accuracy of the proposed scheme can meet the measurement requirements,and the efficiency is higher than that of the traditional method,which can meet the emergency inspection needs of power lines.
