ANALYSIS OF THE DIGITAL IMAGE OF THE OUTER SURFACE OF A TIRE - TREATMENT OF MISCONCEPTION POINTS

摘要

A method for processing the three-dimensional digital image of the surface of a tire in which the three-dimensional image of said surface is captured by assigning to each pixel of the plane of the image information relating to the elevation of that point by relative 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 carried out using an opening and then a closing, so as to adjust the gray level of the pixels located abnormally above or below the surface to be inspected.
