Abstract
We have developed a visual inspection-system with high speed and accuracy in which the quick matching to a reference image and the judgments whether a product is good or defective are made under changes of a set of good or defective sample images. The system provides a fast pattern-matching function that yields a high-precision estimation of the object position, a robust product-acceptability decision function, and easy operations. The developed system can reduce inspection mistakes or oversights by human inspectors.
