Abstract
A method for inspecting a tire's surface includes: capturing a reference image of a reference tire's surface relief elements and transmitting data of the reference image to a processor; parameterizing main characteristics of the reference image via interaction of an operator with the processor; producing a reference map of the surface relief elements by dividing the reference image into a plurality of reference zones of interest; assigning a specific registration and checking algorithm to each of the reference zones of interest; capturing an inspection image of a tire under inspection; and, after completion of pre-processing of the inspection image, automatically: superimposing the reference map on the inspection image, and, for each of a plurality of zones of interest of the inspection image, running the specific registration and checking algorithm for a corresponding one of the reference zones of interest, to determine a conformity of the tire under inspection.
