基于Canny算法和图像处理的10 kV电缆中间接头典型施工缺陷识别
Gaoya dianqi10 kV电缆中间接头施工缺陷易导致绝缘故障，为了快速准确的检测识别电缆中间接头施工缺陷，提出一种Canny算子和图像处理结合的边缘检测方法。Canny算子和图像处理结合的算法能最优定位边缘、不误检，得到准确的中间接头边缘信息。实验结果表明，Canny边缘算法能检测出缺陷图像中较为完整的污渍和划痕，对于主绝缘切割不齐、半导电剥离不齐和毛刺缺陷能准确的检测，缺陷算法准确率均达到90%以上。Canny边缘检测算法提高了缺陷检测的智能化程度，能有效管控施工质量。

Gaoya dianqi基于无人机航拍的电力巡检成为目前绝缘子缺陷检测方法的主流，但当遇到图像特征不够明显或干扰特征较多等问题时，绝缘子缺陷识别困难，检测精度不高。由此，提出了一种基于改进YOLOv5s的绝缘子缺陷检测方法。首先，重新设计卷积模块，然后将CA注意力机制与其相融合，并且在主干网络加入注意力机制与颈部网络的特征图进行多尺度特征融合，抑制复杂环境下的干扰特征，专注缺陷特征提取；其次，对空间金字塔池化结构（SPPF）进行改进，扩大感受野，减少被模型过滤掉的有用信息；接着，将Transformer与C3模块中的残差结构 ...
