Abstract

L'invention concerne un procédé de génération d'image tridimensionnelle, comprenant : l'acquisition d'un ensemble d'images d'un objet, l'ensemble d'images comprenant au moins une image de départ, une image intermédiaire et une image de fin (S101) ; et l'assemblage séquentiel de l'image de départ, de l'image intermédiaire et de l'image de fin pour obtenir une image tridimensionnelle (S102) Les images de l'ensemble d'images acquises peuvent être assemblées en utilisant le procédé, l'image de départ, l'image intermédiaire et l'image de fin de l'ensemble d'images étant assemblées séquentiellement, formant ainsi une image tridimensionnelle. Le procédé permet de limiter la quantité d'équipement nécessaire pour générer une image tridimensionnelle, est moins coûteux et présente moins d'exigences en ce qui concerne les matériaux formant l'image tridimensionnelle. La quantité de données acquises pour l'image tridimensionnelle est réduite, ce qui facilite l'utilisation et le partage, permettant ainsi d'assembler des images tridimensionnelles en objets de n'importe quelle taille de manière rapide, pratique et économique.
