Abstract

Procédé de génération d'informations concernant un objet en 3D à partir d'au moins une projection en 2D de ce dernier. Le procédé consiste à produire au moins une projection en 2D (40) d'un objet en 3D, à générer un groupe de nombre (50, 60) représentés par: aijk = vi'bik - vj''ajk(i,j,k = 1,2,3), ajk et bjk étant respectivement des éléments des matrices A et B, vi' ainsi que vi'' étant respectivement des éléments des vecteurs v' et v''. Les matrices (50) et les vecteurs (60) décrivant ensemble des paramètres de caméra de trois vues (102) de l'objet en 3D et utilisant ledit groupe pour générer des informations concernant l'objet en 3D (70).
