Design and Implementation of a Surface Defect On-line Detection System for Steel Sheets

The strip surface quality will directly affect the quality of the final product performance and quality. This article studies a kind of strip surface defect detection system based on image processing and pattern recognition. It use a special software design structure and modular design concept. Results show that the software for steel plate surface defects can be online real-time detection and has a high precision, and the system also provide the defect data management, reporting and printing service.
