- Abstract:
-
Broken ends of yarns are difficult to detect due to their small features, which are easily overlooked and confused. To detect defects accurately and efficiently in the appearance of polyester yarn packages, an image acquisition platform with a microscopic camera was designed, and a defect detection algorithm (CenterNet-CBAM) with an attention mechanism and feature fusion was proposed. Two types of confusing target images, yarn hairiness, and broken ends were collected to design an objective model of CenterNet-CBAM, which was compared with four other object detection algorithms, CenterNet, YOLOv4, Faster R-CNN, and SSD. The results show that the industrial microscope camera can acquire the feature of yarn hairiness. The precision of CenterNet-CBAM for yarn hairiness and broken ends is 94.00% and 93.57%, the recall rates are 86.75% and 92.16%, AP values are 92.93% and 92.91%, respectively, and the mAP values are 92.92%. Better results in defect detection compared to other algorithms demonstrate the validity of the experiment method.
