METHODS FOR THE AUTOMATIC DETECTION OF THE MATERIAL OF A SPECTACLE FRAME, READING THE SHAPE OF A FRAME, AND EDGING LENSES BELONGING TO A FRAME

The method comprises the following steps: acquiring an axial dimension of a rim (13,14) of the frame (10) or an axial dimension of a groove (11) in this rim; comparing this axial dimension of the rim or groove with a predetermined threshold value; and deciding the material of the frame from this com...

Zusammenfassung:	The method comprises the following steps: acquiring an axial dimension of a rim (13,14) of the frame (10) or an axial dimension of a groove (11) in this rim; comparing this axial dimension of the rim or groove with a predetermined threshold value; and deciding the material of the frame from this comparison. Le procédé comporte les étapes suivantes : acquisition d'une dimension axiale d'un cercle (13,14) de la monture (10) ou d'une dimension axiale d'un drageoir (11) de ce cercle; comparaison de cette dimension axiale du cercle ou de cette dimension axiale du drageoir avec une valeur seuil prédéterminée; détermination du matériau de la monture en fonction de cette comparaison.
