摘要
输电线路作为输送电能的桥梁,线路的安全稳定运行关系着整个电网的正常运转。弧垂作为评价线路运行状况的一项重要指标,定期测量线路弧垂的变化可以有效降低安全隐患。本文提出一种基于双目视觉技术的弧垂测量方案,提取线路中的特征点并进行匹配和重建,最终通过拟合曲线计算弧垂,该方案具有较快的测量速度和较高的测量精度。
The transmission line is regarded as the bridge of energy transport,it is great importance to ensure the safe and reliable operation of them,which is directly related to the normal operation of the grid.Sag as an important indicator of the health of the transmission line,Periodically measuring the change of the line can effectively reduce security risks.This paper proposes a sag measurement scheme based on binocular vision technology,extract the feature points and do matching and reconstruction,caculate the sag by curve fitting,the scheme has a fast measurement speed and high precision.
