Abstract (en)
[origin: WO2010052196A1] The invention relates to a device for acquiring the digital relief image of the surface of a tyre P, said device including: two colour cameras for acquiring stereoscopic images (13a, 13b), each including N primary image sensors (131a, 132a, 133a, 131b, 132b, 133b) for a given primary colour (R, G, B), N being greater than or equal to two, said cameras being arranged so as to acquire the light transmitted (E) towards a predetermined area (Z) of the tyre surface using lighting means (231, 232, 233), and reflected (F) by said tyre surface; N lighting means (231, 232, 233) simultaneously projecting, each independently and along the same direction onto said area (Z) of the tyre surface, light having a wavelength that corresponds to one of the primary colours (R, G, B) of the cameras according to a fringe system (S1, S2,.. SN) alternating lit bands and unlit bands having a given width (L1, L2,... LN).
