METHOD AND DEVICE FOR TESTING AN INSPECTION SYSTEM FOR DETECTING SURFACE DEFECTS

摘要

Systems and methods that check inspection systems for proper detection of surface defects without impairing production processes are needed. In many cases, the disclosed systems and methods concern detection of surface defects in flat steel products. One example method involves generating a photograph of a surface of a product with a camera, transmitting the photograph in digital form to an image processing device, integrating a digitized representation of a surface defect into the digitized photograph, performing fault detection in the image processing device based on the photograph and the digitized representation of the surface defect, and determining whether the image processing device properly detected the digitized representation of the surface defect as a fault of the surface of the product.
