摘　　要：传统的高压线悬高测量多以全站仪为主,不仅测量效率低,而且测量精度和准度也无法得到保证。本文以实际工程为例,结合无人机激光雷达数据对高压线悬高进行测量,首先对外业采集的数据进行预处理,分类得到地面点和高压线点云,再将点云切片投影后,得到高压线悬高点及竖直方向上对应的地面点,最后完成了对高压线悬高的测量。本文将无人机激光雷达测量结果,同全站仪测量结果进行了对比,证明了方法的可行性。The traditional suspension height measurement of high voltage line is mainly based on total station.The measurement efficiency of total station is not only low,but also the measurement precision and accuracy can not be guaranteed.This paper takes the actual project as an example,combined with the UAV point cloud data to measure the suspension height of high voltage lines.Firstly,the data collected by the external industry are preprocessed,and the ground point and high voltage line point cloud are obtained by classification.After the point cloud section is projected,the suspended height of the high voltage line and the corresponding ground points in the vertical direction are obtained.Finally,the suspension height of high voltage line is measured.This paper compares the measurement results of UAV point cloud with those of total station to prove the feasibility of the method.
