An antenna array includes a plurality of first antenna elements and second antenna element(s). The first antenna elements operate at least in a first frequency band and a second frequency band, and any frequency in the second frequency band is higher than any frequency in the first frequency band. The second antenna element(s) operate at least in a third frequency band, and the third frequency band at least partially overlaps the second frequency band. The first antenna elements are arranged at intervals, and the second antenna element(s) is/are disposed between at least two adjacent first antenna elements. A center distance between every two adjacent first antenna elements is within a preset size range, so that a gain of the antenna array in the first frequency band is greater than or equal to a target value.

A wheel image acquisition assembly includes a base, a motor assembly and a camera module. One end of the base is for being connected to a support body in a wheel positioning apparatus, and the other end of the base is for being connected to the camera module. The motor assembly is mounted in the base and includes a motor for driving the camera module to rotate around the horizontal axis so as to adjust a pitch angle of the camera module. The camera module is used for acquiring image of wheels so as to determine the position of the wheels relative to a vehicle. The wheel image acquisition assembly can drive the camera module to rotate by means of the motor, so as to adjust the visual field range of the camera module, which is more flexible, and facilitates wheel alignment positioning in a complex environment.
