摘要:
A method for evaluating the surfaces of a tire, said surfaces being molded with rigid elements, wherein a collection of N images of a given zone of the tire is constituted based on the images originating from one or more tires, each of the images of the collection being constituted by the values of physical magnitudes measured by a sensor sensitive to the reflection of the light at each of the points with coordinates i, j of said surface, and then the images of said collection are made to correspond by superposition, and the image of the zone of a tire from said collection to be evaluated is compared with a reference image. The value of the physical magnitudes of the reference image is calculated based on the value of each of these physical magnitudes measured on the N images of said collection.
