Abstract

Procédé d'identification d'objets par attribution à un objet de référence par exploration d'une image d'objet étudié et comparaison des informations ainsi obtenues à des informations de référence. Le procédé consiste à mémoriser des informations d'exploration de l'objet sC , puis à déterminer une ou plusieurs grandeurs caractéristiques X1 à X4 et à comparer chacune de ces grandeurs caractéristiques à une grandeur caractéristique Y1 ... Y4 d'au moins un objet de référence R1 ...Rn obtenue de la même manière. Application notamment au triage de pièces pour leur introduction sélective dans des machines d'usinage.
