A brief review of the research and application process of Baosteel's surface inspection technology for strip steel in the past decade, with a focus on Baosteel's machine vision inspectionThe project team independently develops and possesses Baosteel's independent intellectual property rightsBAOVISION－HIS/MDS/SISSeries detection systems and their applications,And the development trend of surface inspection technology for strip steel was also discussed.

Surface defects on strip steel are one of the most important factors affecting the quality of strip steel. In the past two decades, some domestic and foreign steel companiesIndustry and equipment suppliers are focusing on the research of online detection technology for surface quality of strip steel, and as a result, a number of strip steel products have emergedSteel surface quality testing enterprises, such asISRA/Parsytec，COGNEXWait. Detection and control of surface defects on strip steel, for the purpose of removingRemoving waste, reducing raw material waste, improving product yield, and improving labor conditions for workers are all of great significance. And how to proceed in the production processDetecting surface defects in strip steel and controlling and improving the quality of strip steel products has always been a major concern for steel production enterprisesThe problem. Developing an online detection system for surface defects of strip steel based on machine vision can effectively achieve the detection of surface defects in strip steelDetect and identify defects, and determine the quality level of the strip steel based on defect information to meet the varying quality levels of different usersSame requirements. Realize non manual continuous and accurate detection, defect classification, and recording of surface defects on strip steel, and implement themTime control will play a very positive role in improving production efficiency and maximizing final product quality, thereby enhancing the competitiveness of enterprises.
