Abstract
We have developed a full-color inspection system that detects defects such as pin-holes and stains on surface of prepaid cards. The system consists ofa card conveyer unit with an automatic exchange mechanism and a custom designed image processing unit with a three-stage pipeline structure. Inspection performance ofO. 7 seconds/card with a defect detection resolution of 0. 1 5mm diameter is achieved with a new algorithm that reflects human visual criteria.
