Machine vision can ensure reliable, repeatable bar code inspection

摘要

As the standards for product and ingredient quality face ever more stringent agency regulations, bar code reading, verification, and grading are increasingly important in many inspection processes. Commonly used in pharmaceutical applications for traceability purposes, bar codes are now used for a similar purpose in food and beverage applications. They are also more frequently applied in industrial applications, enabling recalled product to be quickly identified and tracked back to its manufacturing origin, easing the recall process.
