Abstract
A method for detecting defects on tires in a tire production process includes providing a tire; acquiring a three-dimensional image of a surface portion of the tire; generating, as a function of the acquired image, a plurality of values indicating the measure of a height profile of the surface portion of the tire; calculating, as a function of the plurality of values of the measure of the height profile and according to a consensus interpolation, a plurality of values indicating an estimation of a reference height profile of the surface portion of the tire; calculating, as a function of the plurality of values of the measure of the height profile and of the estimation of the reference height profile, a height profile of possible defects in the surface portion of the tire; and comparing values of the height profile of possible defects with respect to a threshold value in order to detect possible defects in the surface portion of the tire.
