摘要： A for inspecting the internal surface located between a first and a second bead of a tire (P), comprising means for acquiring the image of the internal surface (1) of the tire, and centering means that are able to lock the first bead around its entire circumference on a reference plate, and to set the tire into relative rotation about its axis XX′ with respect to said image acquisition means. This device comprises means for opening and for holding the second bead, said means comprising two internal holding rollers (32, 32) which have a generally radial axis, and at least one external holding roller (33) which has a generally radial axis, is disposed substantially in the middle of the angular sector formed by the two internal holding rollers (31, 32) and is able to come into abutment against the external part of said second bead, the internal (31, 32) and external (33) holding rollers being mounted so as to rotate as one about the axis XX′ of said image acquisition means (1).

摘要： Method for inspecting a zone of the surface of a tire, said surface comprising markings in relief, wherein the three-dimensional profile of the surface to be inspected is determined, characteristic points on the surface to be inspected are located and these points are matched with the corresponding points originating from the three-dimensional data of a reference surface, so as to create a set of pairs of matched points, in an iterative manner, a first affine transformation function is sought, applied to the characteristic points of the reference surface, so that the value representing the sum of the distances between each of the characteristic points of the reference surface, which points are transformed with the aid of said first transformation function, and the points of the surface to be inspected that are matched with them, is minimal, and said first transformation function is applied to all of the points of the reference surface in order to obtain a transformed reference surface.
