ANALYSIS OF THE DIGITAL IMAGE OF THE EXTERNAL SURFACE OF A TYRE AND PROCESSING OF FALSE MEASUREMENT POINTS

摘要

Method for processing the three-dimensional digital image of the surface of a tyre in which the three-dimensional image of the said surface is captured while assigning to each pixel of the plane of the image an item of information relating to the elevation of this point with respect to the surface to be inspected, characterized in that, with the aid of a morphological operator using a structuring element, a first transformation of the image of the surface is performed with the aid of an opening and then of a closing, so as to tailor the grey level of the pixels situated abnormally above or below the surface to be inspected.
