ECARA-YOLO:An improved printed circuit board defect detection algorithm
摘要
Abstract
As the foundation of the electronic information industry,the quality of printed circuit boards hada decisive impact on the subsequent production of electronic products.However,due to the influence of complex background,subtle defects and irregular shape of printed circuit boards,the existing defect detection of printed circuit boards had problems such as missed detection and false alarm.To solve the above problems,an improved printed circuit board defect detection algorithm ECARA-YOLO was proposed.An efficient channel attention mechanism was introduced,and an adaptive local interaction strategy was used to capture spatial information and enhance the ability to extract the features of small target defects.In addition,a feature fusion network ARANeck was designed by combining the efficient channel attention mechanism and the content-aware feature recombination module.In the content-aware feature recombination module,semantic information and content information were combined and sampled,and target focus was realized through efficient attention mechanism,which made small target defect detection more comprehensive and efficient.Experimental results showed that the improved algorithm had a mAP index of 96.2%,which was 7.1%,9.2%,3.9% and 1.9% higher than the four classical models Fast-RCNN,YOLOv4,YOLOv5s and YOLOv8,respectively.Compared with four classical models,ECARA-YOLO had significant advantages in the detection of six types of defects.Compared with the existing methods,the proposed algorithm effectively improved the detection accuracy of small defects of printed circuit boards in complex environments,and had certain reference value in the field of industrial detection research.关键词
