Abstract

PROCÉDÉ DE SEGMENTATION AUTOMATIQUE D’UNE ARCADE DENTAIRE L’invention concerne un procédé de segmentation automatique d’une arcade dentaire comprenant une acquisition d’une surface tridimensionnelle de l’arcade dentaire, pour obtenir une représentation tridimensionnelle comprenant un ensemble de vertex, une génération de vues virtuelles à partir de la représentation tridimensionnelle, une projection de la représentation tridimensionnelle sur chaque vue virtuelle bidimensionnelle, pour obtenir une image représentant chaque vertex sur la vue virtuelle, un traitement de chaque image par un réseau d’apprentissage profond, une projection inverse de chaque image pour attribuer à chaque vertex de la représentation tridimensionnelle, un ou plusieurs pixels des images dans lequel le vertex apparait et auquel il correspond, et en attribuant à chaque vertex un ou des vecteurs de probabilité, une détermination de la classe de tissu dentaire à laquelle appartient le plus probablement chaque vertex à partir du ou des vecteurs de probabilité.
