Abstract

L'invention se rapporte à un procédé pour former les contours tridimensionnels d'une surface, fondé sur une technique de projection de franges sur écran complet. On utilise un système vidéo numérique (18) pour projeter sur un objet (12) des motifs de franges, créés par procédé numérique. Le motif de franges, déformé par la géométrie de la surface (14) de l'objet, est ensuite capturé par une caméra CCD haute résolution (20). Afin d'augmenter la résolution de la formation des contours, on utilise une technique numérique de déphasage entièrement basée sur le logiciel, ce qui rend superflus les systèmes de positionnement précis, utilisés dans les techniques de déphasage traditionnelles. On reconstruit ensuite la surface (14) en appliquant des algorithmes d'habillage et de déshabillage de phase.
