Abstract
A method for checking a tyre in a tyre production line. A portion of outer surface of the tyre is deformed to form an elastically deformed portion of inner surface and an elastically deformed portion of outer surface while illuminating the elastically deformed portion of outer surface with a first diffused light radiation emitted by a first light source and illuminating the elastically deformed portion of inner surface with a second grazing light radiation emitted by a second light source. Images of the deformed and illuminated portions of outer and inner surfaces are acquired through cameras, and the tyre is set in relative rotation around its rotation axis with respect to the first and second light sources during deformation and illumination.
