摘　　要：输电线路铁塔跳线长度测量的准确性是影响电力系统稳定运行的关键问题之一。传统测量方法存在精度不足、操作复杂和误差较大等问题。为提高跳线长度测量的精度和效率,提出了一种基于可见光图像三维建模技术的跳线计算方法。该方法借助特征提取、运动结构恢复和稠密重建技术,实现了对铁塔的精确三维建模,并通过悬链线模型模拟跳线长度,在跳线安装前进行精确模拟。实验结果表明,该方法在跳线长度测量中具有较高的可行性和精确性。与其他三维建模方法相比,该方法在精度与效率之间取得了良好的平衡,能够较好地满足实际工程需求。The accuracy of measuring the jumper length of transmission line towers has been a critical factor affecting the stable operation of power systems.Traditional measurement methods often suffer from insufficient precision,complexity,and susceptibility to human error.To enhance the accuracy and efficiency of jumper length measurement,a 3D modeling technique based on visible light imagery is proposed.This method leverages feature extraction,structure from motion,and dense reconstruction techniques to achieve precise 3D modeling of the jumper,and simulates the jumper length using the catenary model,providing an accurate pre-installation simulation.Experimental results demonstrate that this method performs in capturing the spatial position and dimensions of both the tower and the jumper,significantly improving measurement accuracy and efficiency.Compared to existing techniques,this approach achieves a favorable balance between accuracy and efficiency,meeting the practical demands of engineering applications effectively.
