Abstract

L'invention concerne un outil permettant de commander un processus de création de données de forme de visage ('FDV') pour chirurgie plastique virtuelle. L'outil décrit comporte une série de modules de calcul qui sont capables d'exécuter de manière automatique et successive les étapes nécessaires à un processus complet de fusion FDV, par exemple une étape de fusion, une étape de correction d'une zone de jointure, une étape de correction d'une zone de trous, une étape de correction du nombre de polygones, une étape de correction de la qualité de maillage etc. conformément à des informations de base permettant un calcul de fusion auto-défini et ne nécessitant pas de calcul complémentaire de la part de l'utilisateur. Ces modules peuvent être installé de manière flexible et interconnectable dans un élément d'un dispositif électronique associé à un dispositif photographique tel qu'une caméra de saisie d'images, et à un générateur de formes. Cet outil permet à un établissement médical d'assurer facilement la création de formes FDV tridimensionnelles à partir d'un objet sensiblement plastique représentant le visage d'un client, sans nécessiter de connaissances spécialisées particulières se rapportant au processus de fusion d'une image tridimensionnelle, ce qui permet l'utilisation aisée et essentielle du processus FDV pour une intervention plastique virtuelle (traitement médical), et une commodité d'accès optimale de l'établissement médical (et du client) à la chirurgie plastique virtuelle,.
