Abstract
Surface defects of steel materials affect product quality and industrial safety. High-precision and high-efficiency detection of surface defects in steel is a necessary condition for the high-quality development of the steel industry. Therefore, this paper reviews the research work related to steel surface defect detection and lightweighting. Starting from the data sets, it then elaborates on the defect development of traditional detection technologies, followed by a summary of detection based on machine learning and deep learning. The optimization approaches and lightweighting technologies represented by the YOLO series, such as structural optimization, model compression, and auxiliary strategies, are emphasized and elaborated on as the key points. Moreover, YOLO series model cases are used for illustration, and the effects after different improvement methods in the three cases are analyzed and compared. The YOLOv8-CSG has a better balance: the computational cost is reduced by 37% and the parameter quantity is reduced by 35.2%; for the improvement of the YOLOv8 model, the optimal compression is mentioned: the model size is reduced by 44%, and the lightweighting methods have improved the detection accuracy, detection efficiency, and real-time performance. Finally, the relevant technologies for detecting surface defects of steel were briefly summarized, and the future development of these technologies was also prospected.
