Periodic Defects in Steel Strips: Detection Through a Vision-Based Technique

摘要

As steel strips produced in steel works are used as raw material in many other industries, control of their quality is essential. Steel is required for the production of many products such as tools, cans, or car parts. In all of these cases, the quality of the steel has a direct impact on the quality of the final product. One of the most critical phases of steel quality control takes place in the finishing mill, where the hot steel is rolled into its final form. If the roll surface that applies pressure on the steel has any kind of distortion, it imprints a set of defects on the steel strip. Each time it completes a turn, it generates a defect. This is a crucial problem.
