3-DIMENSIONAL MEASURING SYSTEM OF A TIRE, CAPABLE OF MEASURING THE DEFORMATION OF A TIRE OF A VEHICLE TO MEASURE THE 3-DIMENSIONAL DEFORMATION AT A LOCAL BLIND SPOT OF A TIRE

摘要

PURPOSE: A 3-dimensional measuring system of a tire is provided to measure the deformation of a tire at a local blind spot of a tire by using reflection and refraction of light with a mirror including a convex lens.;CONSTITUTION: A 3-dimensional measuring system of a tire(2) comprises: a light projection unit which projects light on the tire including a predetermined pattern on the tire; a mirror which is shaped of a convex lens; a photographing unit which obtains tire image data from the light reflected from the tire through the mirror; and an arithmetic unit(5) which receives the tire image data from the photographing unit and produces the 3-dimensional coordinates of the shape of the tire. The arithmetic unit traces the change of the pattern on the tire.;COPYRIGHT KIPO 2010
