Abstract

A method and apparatus for checking tyres in a tyre production line. The method includes alternately illuminating, with a first and second grazing light radiation, a surface portion of the tyre and respectively acquiring a first and second two-dimensional digital image of the illuminated surface portion. For each point of the surface portion, the respective overall light power of the first and second light radiation incident at the point respectively comes from two half-spaces that are opposite with respect to an optical plane passing through the perpendicular to the surface at the point; and comparing the first and second image to obtain information on an altimetric profile of the surface portion.
