中文摘要:针对现有的巡检机器人缺陷图像识别检测算法不能充分融合特征金字塔网络多层特征的问题，提出了一种基于金字塔多层特征自适应的变电设备缺陷图像识别检测算法。首先，构建出一种新的RoI特征金字塔结构用以提取各个层级的变电设备缺陷图像特征图；其次，设计出一种多层特征自适应学习函数来自动学习不同层级特征权重;最后，结合目标大小尺度检测框架实现变电站缺陷图像区域检测。所设计的方法增强了变电设备缺陷图像检测的鲁棒性。实验结果显示，所提方法的mAP达到了71.9%。

Substation Equipment Defect Detection based on Pyramid Multi level feature adaptation

Abstract:In order to solve the problem that the existing defect image recognition and detection algorithm can not fully integrate the multi-layer features of the pyramid network, an adaptive pyramid multi-layer feature based defect image recognition and detection algorithm is proposed for substation equipment. Firstly, a new ROI feature pyramid structure is constructed to extract the defect image feature map of each level of substation equipment; secondly, a multi-layer feature adaptive learning function is designed to automatically learn the feature weights of different levels; Finally, the substation defect image region detection framework is designed. Our proposed method improve the robustness of defect detection. Extensive experiments show that our method achieve recognition and detection mAP accuracy of 71.9%.
