Abstract
Method for checking a tyre. The method includes associating first and second independent light sources with a camera, applying a first force against a first surface portion of the tyre to generate a first deformed surface portion, and illuminating the first deformed surface portion with a first light radiation emitted by the first light source while keeping the second light source deactivated. A first image of the first deformed surface portion is then acquired by the camera. The first force is removed and a second surface portion partially distinct from the first surface portion is illuminated with a second light radiation emitted by the second light source without deforming the second surface portion. A second image of the second surface portion is then acquired by the camera. The first and second images are processed for detection of possible defects in the first and second surface portions.
