Abstract

This paper is concerned with the problem of how to detect visual defects on painted slates using an automated visual inspection system. The inspection work cell of the manufacturing process was replicated by mounting the inspection system on an industrial conveyor and operating at production line speeds. Laboratory test bed proven image sensing methods and inspection algorithms were subjected to robustness testing in an environment similar to that found in the factory. The additional challenges introduced by a factory-type test-bed are discussed in detail.
