Abstract
The present invention relates to a device (10) for checking a tyre (200), the device (10) comprising: a detection system (104) comprising a camera (105) having an optical plane (107) passing through the camera (105) and defining a focal plane (121); a first light source (110), a second light source (108) and a third light source (109) adapted for emitting a first light radiation, a second light radiation and a third light radiation, respectively to illuminate a surface portion of said tyre at or close to said focal plane (121), said second light source (108) and said third light source (109) being arranged at opposite sides with respect to said optical plane (107); where said first light source (110) is fixed with respect to said detection system (104) and said second light source (108) and third light source (109) are adapted to be movable from a first inactive configuration where they are controlled to not emit said second light radiation and third light radiation and wherein the distance (d2, d3) of said second light source (108) and of said third light source (109) from said focal plane (121) is greater than the distance (d1) of said first light source (110) from said focal pla…
