Abstract

As the carrier of electric energy transmission, transmission lines undertake the important task of electric energy distribution and transfer. However, with the increasing frequency of construction using large machinery such as tower cranes and excavators under the transmission channels, transmission line accidents occur frequently. Therefore, this paper proposes a refined identification method for the hidden dangers of external damage in transmission lines based on the generation of effective regions driven by vanishing points. The comprehensive and accurate perception of external damage targets through the perception model of scene elements based on slicing-aided hyperinference was realized. Secondly, the accuracy and robustness of the calculation of the transmission line’s vanishing point were improved based on Canny edge detection and Hough linear detection. The effective region on the visual images was generated by combining the vanishing point and the bottom of transmission tower coordinates. Finally, the relative position relationship between areas with hidden dangers of external damage and the effective warning regions were compared, and the refined identification of hidden dangers was realized. The experimental data show that the proposed method realized a perception accuracy of 82.9% in identifying hidden dangers of external damage caused by ground- and aerial-moving targets, which shows better detection performance and practical value compared with the existing method.

基于产生消失点驱动有效区域的输电线路外部损坏隐患精细识别方法

输电线路作为电能传输的载体，承担着电能分配和输送的重要任务。然而，随着塔吊、挖掘机等大型机械在输电通道下施工的日益频繁，输电线路事故频发。因此，本文提出了一种基于消失点驱动的有效区域生成的输电线路外力破坏隐患精细化识别方法。通过基于切片辅助超推理的场景元素感知模型，实现了对外部损伤目标的全面准确感知。其次，基于 Canny 边缘检测和 Hough 线性检测，提高了输电线消失点计算的准确性和鲁棒性。结合消失点和输电塔底部坐标，生成了可视图像上的有效区域。最后，比较了外力破坏隐患区域与有效警示区域的相对位置关系，实现了隐患的精细化识别。实验数据表明，所提出的方法在识别地面和空中移动目标造成的外力破坏隐患方面的感知准确率达到了 82.9%，与现有方法相比具有更好的检测性能和实用价值。
