Title (EN) METHOD FOR READING AN IDENTIFICATION CODE ON A GLASS SHEET
(FR) PROCEDE DE LECTURE D'UN CODE D'IDENTIFICATION SUR UNE FEUILLE DE VERRE
Abstract:
(EN) A method for reading symbols forming code each marked on one face of sheets of glass close to a same edge of the sheets of glass, the sheets of glass being disposed in a stack. The method comprises: -acquiring, with a camera, at least one image through said edge of the sheets of glass, the direction of observation being non-perpendicular and inclined relative to said edge of each of the sheets of glass of which the code needs to be read using said image; -an image processing step in which the acquired image is processed by a computer programmed in such a way as to extract the information present in at least one code visible on the image and needing to be read.
(FR) Procédé de lecture de symboles formant code marqués chacun sur une face de feuilles de verre à proximité d'une même tranche des feuilles de verre, les feuilles de verre étant disposées en une pile. Le procédé comprend: -une acquisition, avec une caméra, d'au moins une image par ladite tranche des feuilles de verre, la direction d'observation étant non perpendiculaire et inclinée par rapport à ladite tranche de chacune des feuilles de verre dont le code doit être lu avec ladite image; -une étape de traitement d'image dans laquelle l'image acquise est traitée par un calculateur programmé de façon à extraire l'information présente dans au moins un code visible sur l'image et devant être lu.
