Abstract

Des modes de réalisation de l'invention concernent un procédé d'enregistrement de visage et un dispositif d'enregistrement de visage destinés à obtenir un modèle de visage plus complet, avec des restrictions réduites pour les gestes de l'utilisateur pendant la comparaison, et un taux de réussite amélioré de la vérification. Le procédé dans les modes de réalisation de l'invention comprend les étapes suivantes : un dispositif d'enregistrement de visage reçoit un message d'enregistrement, détecte si un visage d'un utilisateur existe dans une période de temps prédéfinie, et si tel est le cas, collecte une première caractéristique faciale lorsque le visage est dans une première position ; le dispositif d'enregistrement de visage génère des premières données de modèle de visage en fonction de la première caractéristique faciale ; le dispositif d'enregistrement de visage stocke les premières données de modèle de visage dans un dispositif de stockage ; le dispositif d'enregistrement de visage collecte une seconde caractéristique faciale du visage lorsqu'un angle de rotation d'une seconde position atteint une valeur prédéfinie après que le visage a tourné par rapport à la première position ; le dispositif d'enregistrement de visage obtient des secondes données de modèle de visage en fonction de la seconde caractéristique faciale ; et le dispositif d'enregistrement de visage stocke les secondes données de modèle de visage dans le dispositif de stockage.
