基于RTK无人机搭载激光雷达模块测量导线弧垂算法研究与应用
Research and Application of Wire Sag Measurement Algorithm Based on RTK UVA Equipped with LiDAR Module
摘要
Abstract
This paper explores the algorithm research and application of RTK UVA calculation technology in sag measurement of transmission line conductors.During the construction and acceptance process of transmission lines,wire sag is an important parameter indicator.Traditional measurement methods suffer from terrain limitations,cumbersome operations,obstructed field of view,and significant errors.By utilizing the flexible flight capability of RTK UVA and equipped with LiDAR measurement technology,high-precision positioning of wire measurement points can be achieved in real-time and dynamically.Based on the theory of longitude and latitude ranging,a parabolic three measurement points and multiple measurement points are used to calculate wire sag.By comparing and analyzing the difference between a line selection coefficient k and its standard value,the narrow range of k value variation is determined to verify the accuracy of wire sag measurement.At the same time,the ideal division of measurement sections using RTK UVA is provided to complete the high-precision wire sag measurement,providing a new solution for wire sag measurement.This technology not only breaks through environmental limitations,improves measurement efficiency,but also reduces the risk and cost of manual measurement,which provides an efficient measurement method for the field of transmission lines,and helps to improve the construction efficiency of transmission lines,therefore providing strong support for the sustainable development of the power industry,which has broad application prospects.关键词
