A detection device (7a) for determining the orientation of a first and a second wheel (2) of a vehicle (3), the wheels being arranged on a first side of the vehicle (3) with respect to a longitudinal axis thereof (A). The device is set laterally with respect to the vehicle (3) on the first side, between the first and second wheels, and has a first (8) and a second image-acquisition elements (8') located on a base support (16) having a respective viewing area (V) for acquiring images of a first and a second target (5) coupled to the first and second wheels, respectively. A displacement unit (10) is operatively coupled to the first (8) and second (8') image-acquisition elements for rotating them simultaneously through one and the same angle of rotation so as to adapt their viewing area to the position of the first and second targets (5). The detection device (7a) further comprises additional alignment sensors (27a, 27b, 28a, 28b) also located on the base support (16) for measuring calibration parameters of the base support (16). |
