Industrial colour inspection by video camera

Advances in video camera technology, coupled with techniques developed at the University of Huddersfield, allow video cameras to be used as colour measuring instruments. Cameras are non-contact sensors, and can therefore be used on-line without disrupting production. On-line inspection enables a faster response to faults, saving waste and improving quality. The paper describes the research done at the University of Huddersfield, presents the results of laboratory tests and addresses two particular industrial applications.<
