Abstract
Acquisition device for taking a digital relief image of the surface of a tire having two color cameras for the acquisition of stereoscopic images. Each camera has N primary image sensors in a given primary color (R, G, B), where N is equal to or greater than two. Each camera is placed so as to acquire the light emitted (E) towards a predetermined area (Z) of the surface of the tire by N lights and reflected (F) by the surface of the tire. The N lights simultaneously project each independently and along the same direction onto the predetermined area of the surface of the tire. The projected light has a wavelength that corresponds to one of the primary colors of the cameras, according to a fringe system (S, S, . . . S) consisting of an alternation of illuminated and non-illuminated bands of given width (L, L, . . . L).
