| description | The invention particularly relates to an appearance quality detection method based on machine vision. The method comprises the following steps: loading a template image of a packaging box of a current detection model in a template library; collecting a surface image of the packaging box after the characters and the patterns are printed; correcting the surface image of the packaging box to a system default detection position; carrying out adaptive threshold segmentation processing on the packaging box surface image corrected to the standard detection position, and separating the character region C1 and the pattern region P1 through a standard character region template image; and processing the separated character region C1 and pattern region P1 to judge whether the product is a qualified product or not. Characters and patterns are separated, character defect detection is mainly used for judging whether a product is qualified or not by searching for character bonding and missing, pattern defect detection is mai |
