ARTICLE VISUAL INSPECTION DEVICE

WIPO Patent Application WO/2006/080263

A1

An article visual inspection device capable of detecting that the surface conditions of an article are so inferior as to render it non-usable and rejecting it as a defective article by inspecting it for external defects, occurring on the surface of the article, such as streaks, dice marks and rough surfaces of an aluminum extruded shape material. The visual inspection device comprises an imaging device (1) for imaging the surface of an article, and an image processing device (3) for capturing the picked up image, wherein the image processing device (3) has a plurality of image processing units that compare a captured image with a set judging reference value to evaluate the result, whereby the quality of surface conditions is evaluated based on external defects such as streaks, dice marks and rough surfaces of an aluminum extruded shape material, and evaluations by respective image processing units are weighted by a weighting unit to thereby comprehensively judge whether to accept or reject the article.
