Abstract

In order to address the problems of impact and low signal-to-noise ratio of layered defects in automotive aluminium alloylined carbon fibre fully-wound hydrogen storage composite cylinders, we propose a deep learning algorithm based on YOLOv7. The algorithm introduces the Swin-Transformer module into the YOLOv7 backbone network structure to capture the contextual information and global dependencies of steel surface defects at different scales to retain more feature information of small-scale targets, thus improving the detection accuracy of the model. At the same time, we use the ECA attention module to improve the network's attention to small targets, which effectively solves the problem of the original model's missed detection of small targets. Finally, partial convolution (PConv) is introduced in the neck network of the model to replace the regular convolution for lightweight improvement to reduce the number of parameters and computation of the model. The experimental results show that the detection accuracy of the algorithm reaches 98.3% on the infrared thermal imaging dataset of homemade automotive hydrogen storage composite gas cylinders, which is 6.2% higher than that of the original YOLOv7 algorithm, and the algorithm has better detection accuracy and detection rate, and it can play an important role in industrial applications
