Abstract
Apparatus for checking a tyre having: a support plane; a deformation element to generate a deformed surface portion; a positioning actuator to move the deformation element; and a device with a camera, a first light source, a second light source, a processing unit and a drive and control unit. The processing unit is programmed to activate the positioning actuator to move the deformation element towards the tyre to generate a deformed surface portion. The drive and control unit is programmed to: actuate the first light source to illuminate the deformed surface portion of the tyre, the second light source being inactive during the deformation; control the camera to acquire a first image of the deformed surface portion; actuate the second light source to illuminate an undeformed surface portion of the tyre; and control the camera to acquire a second image of the undeformed surface portion.
