The invention relates to a method for the automatic grading of articles, such as garments. For an article of a given type, such as a garment, the invention comprises the use of: (i) a grading mask comprising images of pieces of a reference article, in the form of geometric areas which each contain one or more characteristic points of a piece of the reference article; and (ii) grading formulas which are associated respectively with the different areas. According to the invention, each formula can be used to determine a movement to be applied to each characteristic point in the associated geometric area in order to move from the base size to another size, each of said formulas being a function of the variation in one or more values on a body measurement chart or a pre-determined increment value. The inventive method comprises the following steps consisting in: obtaining images of the pieces of the article to be graded for a size corresponding to the base size of the mask, placing said images on the mask in positions corresponding to those of the pieces of the mask and automatically grading the pieces using the mask formulas and a selected body measurement chart.

Pour un article d'un type donné, notamment un vêtement, on utilise un masque de gradation comportant des images des pièces d'un article de référence, des régions géométriques contenant chacune un ou plusieurs points caractéristiques d'une pièce de l'article de référence, et des formules de gradation associées respectivement aux différentes régions, chaque formule permettant de déterminer, dans la région associée et en fonction de la variation d'une ou plusieurs grandeurs d'un barème de mensurations ou d'une valeur d'incrément prédéterminée, un déplacement à appliquer à chaque point caractéristique contenu dans cette région pour le passage de la taille de base à une autre taille. On appelle des images des pièces de l'article à grader pour une taille correspondant à la taille de base du masque, on place ces images sur le masque dans des positions correspondant à celles des pièces du masque, et on réalise automatiquement la gradation des pièces à partir des formules du masque et d'un barème de mensurations choisi.
