Abstract

The purpose of this study is to propose a method based on three-dimensional laser scanning and frame difference technology to measure the inclination of transmission line towers, so as to realize accurate monitoring of transmission line structure. Firstly, the multi-scale Retinex algorithm is used to enhance and preprocess the transmission line tower image to improve the image quality. Secondly, the method of frame difference and background difference is combined to detect and identify the inclined tower. Finally, the point cloud data of inclined tower is obtained by using three-dimensional laser scanning technology, and the inclination of transmission line tower is calculated by coordinates. The experimental results show that this method has high accuracy and reliability, with an error of less than 0.15 × 10−5 and an inclination of less than 0.17°. It is proved that this method can improve the monitoring efficiency of transmission lines, has good effects in engineering practice, and can provide effective means for the safe operation of transmission line structures.

基于三维激光扫描和帧间差的输电线路杆塔倾角测量方法

本研究旨在提出一种基于三维激光扫描和帧差技术的方法来测量输电线路杆塔的倾角，从而实现对输电线路结构的精确监测。首先，采用多尺度 Retinex 算法对输电线路杆塔图像进行增强和预处理，以提高图像质量。其次，结合帧差法和背景差法对斜塔进行检测和识别。最后，利用三维激光扫描技术获得斜塔的点云数据，并通过坐标计算出输电线路杆塔的倾角。实验结果表明，该方法具有较高的精度和可靠性，误差小于 0.15 × 10-5，倾角小于 0.17°。实践证明，该方法可提高输电线路的监测效率，在工程实践中具有良好的效果，可为输电线路结构的安全运行提供有效手段。
