Title
(EN) INSPECTION SYSTEM FOR EXTERIOR ARTICLE SURFACES
(FR) SYSTEME D'INSPECTION DES SURFACES EXTERIEURES D'OBJETS
Abstract
(EN)
A system for automated inspection of article exteriors includes a plurality of video cameras (32). One or more of these video cameras (32) is black and white while at least one is color capable. A strobe light for illuminating a specimen (22) disposed in a specimen area (24) onto which all of the cameras (32) are focused. The strobe allows for each camera (32) to capture a still image of the specimen (22), The black and white cameras (32) capture images which allow determining whether the exterior layout is acceptable. The color camera or cameras (30) captures an image which allows determining whether the coloration of the specimen (22) is acceptable. Specimens (22) are selectively rejected on the basis of these acquired images. The system is particularly useful in inspection of beverage container (22) and their associated labelling.
(FR)
La présente invention décrit un système d'inspection automatique de la configuration extérieure d'objets, comprenant une pluralité de caméras vidéo (32). Au moins l'une de ces caméras (32) est en noir et blanc et au moins l'une d'elles est en couleurs. Une lumière stroboscopique éclaire un spécimen (22) disposé dans une zone à spécimens (24) sur laquelle toutes les caméras (32) sont centrées. Le stroboscope permet à chaque caméra (32) de saisir une image fixe du spécimen (22). Les caméras en noir et blanc (32) saisissent des images qui permettent de déterminer si la configuration extérieure de l´article est acceptable. La (les) caméra(s) en couleurs (30) saisit (saisissent) une image qui permet de déterminer si la coloration du spécimen (22) est acceptable. Les spécimens (22) seront rejetés sélectivement sur la base des images ainsi obtenues. Le système s'avère particulièrement utile pour l'inspection de récipients pour boissons (22) et leur étiquetage associé.
