Abstract

L'invention concerne un procédé de détermination d'une image tridimensionnelle d'un objet (Board), comprenant la projection de plusieurs premières images sur l'objet, chaque première image projetée comprenant des premiers motifs lumineux espacés d'une première période ; l'acquisition, pour chaque première image projetée, d'une première image bidimensionnelle de l'objet ; la projection de plusieurs deuxièmes images sur l'objet, chaque deuxième image projetée comprenant des deuxièmes motifs lumineux espacés d'une deuxième période différente de la première période ; l'acquisition, pour chaque deuxième image projetée, d'une deuxième image bidimensionnelle de l'objet ; et la détection d'une zone translucide de l'objet par comparaison de premiers signaux obtenus à partir des premières images et de deuxièmes signaux obtenus à partir des deuxièmes images, et, pour la zone translucide, la détermination de la hauteur de chaque point de la zone translucide à partir des premiers et deuxièmes signaux.
