THE DUAL SOLUTIONS FOR AUTOMATED STEEL STRIP SURFACE INSPECTION - THE BEST OF MATRIX AND LINE SCAN CAMERAS COMBINING ROBUSTNESS AND SENSITIVITY

摘要

The rapidly increasing quality demands on metal surfaces require new quality assurance tools. The Parsytec dual sensor addresses high-end demands for rolling processes where surface inspection could not be applied satisfactorily before. The benefits of this new inspection technology represent a quantum leap in inspection accuracy and scalability towards future demands and improved usability for quality personnel. Currently, there are two image capture technologies being used for SIS: video cameras and line scan cameras. Both have "obvious" advantages, Video cameras are very robust and can be used for a wide spectrum of materials and surface appearances, while Line scan cameras have a higher sensitivity with a limited usability under practical production conditions, considering the unavoidable line vibrations and strip variations. The Key concept behind the dual sensor is to combine both technologies to show the best solutions for the very highest quality grades.
