Paper Abstract

This paper discusses methods of solving on-line inspection problems which have been developed and applied in two particular areas of industry. The cases studied are the automatic inspection of tinplate strip for visible defects in the presence of regular coding patterns on the surface, and the automatic checking of packaged products for dimensions and integrity of labelling. Both systems comprise electro-optical image scanning equipment and real-time, computer-based signal processing systems. The design philosophy of the image processing systems was in each case influenced heavily by the different functions to be performed, the different characteristics of the optical scanning heads, the presentation and condition of the products to be inspected, and the requirements and normal working practices of factory floor personnel. The designs were also constrained by processing speed and cost considerations.
