Method of creating master data used for inspecting concave-convex figure

摘要: An image of respective figures is cut out by selecting a figure from tire CAD drawings, and an arranging position the set in accordance with distance radial direction form center deformed angle circumferential designated location, so that height regions cut-out set. Then, transformed into having gray scale using information regions, and, at figure, sampled predetermined interval tire, master data are created between intersecting points becomes equal.
