Abstract:
A tire tread, having circumferentially juxtaposed elements separated from one another by identically shaped boundaries and having a least one basic pattern, is inspected by: producing an image of the tire tread; identifying tread wear indicators on the image; grouping together sub-sets of the indicators according to the basic pattern(s) included in the indicators; determining a characteristic point of each of the sub-sets of the indicators; determining a sequence of distances by computing distances between the characteristics points of each of the sub-sets of the indicators; comparing and the sequence of distances with a known sequence of distances between characteristic points of the basic pattern(s) to confirm coincidence thereof; and projecting a shape of a boundary between elements of the tire tread onto a surface to be inspected according to the known sequence of distances between characteristic points of the basic pattern(s).
