Abstract (en)
[origin: WO2012143198A1] The invention relates to a method for processing the three-dimensional digital image of the surface of a tyre, in which the three-dimensional image of the surface is captured and each pixel of the plane of the image is assigned a datum relating to the elevation of this point in relation to the surface to be inspected. The method is characterised in that, with the aid of a morphological operator using a structuring element, a first transformation of the surface is performed, by means of opening followed by closing, such as to adjust the grey scale of pixels located abnormally above or below the surface to be inspected.
