A method for determining wheel alignment parameters of a vehicle wheel arrangement, the method comprising the steps of: - projecting a pseudo-random light pattern onto a surface of the vehicle wheel arrangement, said pseudo-random light pattern comprising a plurality of separately arranged components resulting from a plurality of light beams emitted from a light emitting arrangement (104, 104'), said light emitting arrangement (104, 104') comprising a light source and an optical element comprising a plurality of portions arranged to form a distribution pattern of the light from the light source, said distribution pattern corresponding to the projected pseudo-random light pattern on the vehicle wheel arrangement; - acquiring an image of the pseudo-random light pattern on the surface of the vehicle wheel arrangement; - detecting, from the acquired image, a first component of the pseudo-random light pattern on the surface of the vehicle wheel arrangement; - determining an identity of the first component based on a mutual relationship between the first component and the plurality of separately arranged components by determining an angular displacement between the first component and each of the plurality of separately arranged components; and determining the identity of the first component based on a mutual angular displacement between the first component and each of the plurality of separately arranged components; - comparing the identity of the first component with the distribution pattern formed by the optical element; - determining a first portion of the distribution pattern in the optical element distributing the light beam generating the first component on the vehicle wheel arrangement; and - determining a wheel alignment parameter of the vehicle wheel, the wheel alignment parameter being determined based on a distance between the first portion of the distribution pattern in the optical element and the first component on the surface of the vehicle wheel arrangement. - projecting a pseudo-random light pattern onto a surface of the vehicle wheel arrangement, said pseudo-random light pattern comprising a plurality of separately arranged components resulting from a plurality of light beams emitted from a light emitting arrangement (104, 104'), said light emitting arrangement (104, 104') comprising a light source and an optical element comprising a plurality of portions arranged to form a distribution pattern of the light from the light source, said distribution pattern corresponding to the projected pseudo-random light pattern on the vehicle wheel arrangement; - acquiring an image of the pseudo-random light pattern on the surface of the vehicle wheel arrangement; - detecting, from the acquired image, a first component of the pseudo-random light pattern on the surface of the vehicle wheel arrangement; - determining an identity of the first component based on a mutual relationship between the first component and the plurality of separately arranged components by determining an angular displacement between the first component and each of the plurality of separately arranged components; and determining the identity of the first component based on a mutual angular displacement between the first component and each of the plurality of separately arranged components; - comparing the identity of the first component with the distribution pattern formed by the optical element; - determining a first portion of the distribution pattern in the optical element distributing the light beam generating the first component on the vehicle wheel arrangement; and - determining a wheel alignment parameter of the vehicle wheel, the wheel alignment parameter being determined based on a distance between the first portion of the distribution pattern in the optical element and the first component on the surface of the vehicle wheel arrangement.
