Aiming at the problem in defect detection that effective features cannot be extracted due to different shapes of defect targets in the detected samples, this paper presents a defect detection model based on deep learning, which uses an improved multi-scale feature fusion module to solve the problem of identifying defects of different sizes on the basis of controlling the amount of calculation. By introducing a non-local attention mechanism module, the model’s ability of extracting defect features is enhanced. Furthermore, mixed-supervised training is used in training to explore the relationship between the amount of annotations required by the model and the detection accuracy. This method achieves better accuracy than the state-of-the-art methods on KSDD, KSDD2, and STEEL datasets, and can extract discriminative features for different types of defects. Compared with the state-of-the-art fully supervised and unsupervised methods, the average accuracy improvement on the dataset is 0.8% and 11%.
