Abstract
PROCEDE D’AUTHENTIFICATION D’UN ELEMENT OPTIQUEMENT VARIABLE L’invention concerne un procédé de contrôle d’un élément optiquement variable candidat, comprenant : - Enregistrer une séquence d’au moins deux images individuelles candidates dudit élément candidat, par un dispositif de vérification qui comprend un objectif optique, la séquence étant obtenue par un déplacement relatif du dispositif de vérification par rapport audit élément candidat le long d’au moins une trajectoire de vérification, Caractérisé en ce qu’il comprend en outre : - Sélectionner un ensemble de N points de contrôle sur chaque image individuelle candidate, chaque point de contrôle comprenant un unique pixel ou un ensemble de pixels adjacents deux à deux, la position de chaque point de contrôle sur chaque image individuelle candidate étant identique et prédéterminée par un ensemble de coordonnées enregistrées dans une mémoire,- Pour chaque image individuelle candidate, enregistrer la luminosité des pixels de chaque point de contrôle, le long d’au moins une trajectoire de vérification,- Pour chaque point de contrôle, comparer l’évolution de la luminosité des N points de contrôle deux à deux le long de la trajectoire de vérification, dans des conditions d’illumination similaires ; et - Emettre un signal d’alarme en fonction du résultat de la comparaison.
