摘要 当前输电线路显著性目标检测已取得重大突破,但在预测显著区域的“完整性”上仍存在局限性,难以完全识别及定位输电线路上绝缘子串缺陷。本文利用完整性感知网络来检测输电线路上绝缘子串,首先通过特征聚合模块来提取不同层次的特征,其次通过完整性增强模块突出显著目标通道并抑制其他干扰通道,最后通过部分-整体检验模块来确定目标特征的部分和整体是否有强烈的一致性,可提高有缺陷绝缘子串的识别准确率。本文算法与目前公开的3种流行算法进行主客观对比,发现本文算法在绝缘子串与背景融合程度较高时的显著性检测上更有优势。 At present,significant breakthrough has been made in the detection of significant objects of transmission lines,but there are still limitations in predicting the"integrity"of significant areas,and it is difficult to fully identify and locate the defects of insulator strings on transmission lines.In this paper,integrity awareness network is used to detect insulator strings on transmission lines.First,feature aggregation module is used to extract features at different levels.Second,integrity enhancement module is used to highlight significant target channels and suppress other interference channels.Finally,part whole inspection module is used to determine whether there is a strong consistency between parts and the whole of target features,which can improve the recognition accuracy of defective insulator strings.Through subjective and objective comparison between the algorithm in this paper and the three popular algorithms currently disclosed,it is found that the algorithm in this paper has more advantages in the significance detection when the insulator string and background are highly integrated.
