- Abstract:
-
In order to solve the problem of low efficiency of steel defect detection and economic loss caused by false detection, an improved YOLOv5 algorithm was proposed for steel defect detection.Under the condition of keeping the original YOLOv5 detection layer unchanged, the improved algorithm added three auxiliary branches with adaptive weights to extract the shallow information of the YOLOv5 network, and the auxiliary branches could also enhance the gradient flow of the whole network, which made the training effect better. The EMA attention mechanism was added to the main part of the network, and the weighted feature information of the EMA module could help the model better focus on and understand the important target features. SIoU was used instead of the CIoU loss function, and the angle loss and shape loss introduced by SIoU could make the anchor frame more fast and accurate in the regression process to improve the stability and robustness of the detection. Through experiments on the NEUDET dataset, the proposed algorithm had an accuracy improvement of 3. 7 percentage points compared with the original YOLOv5s, and had better detection performance than other mainstream algorithms.
