A vehicle wheel alignment system and method is provided for performing a rolling wheel axis of rotation and wheel spindle point calculation every time an alignment is performed. Embodiments include an aligner having a target fixedly attachable to a wheel of the vehicle; a camera for viewing the target and capturing image data of the target; and a data processor. The data processor receives the image data from the camera, and determines a vector pointing from the target origin to a wheel spindle point based on the captured target image data, when the vehicle is rolled while the wheel is on a substantially flat surface such that the wheel and target rotate a number of degrees. The data processor is further adapted to calculate an alignment parameter for the vehicle based at least in part on the wheel axis of rotation and the coordinates of the wheel spindle point.
A wheel alignment method for a vehicle, the method comprising:
A vehicle wheel alignment system comprising:
A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor of a vehicle wheel alignment system cause the processor to determine an alignment parameter for the vehicle, the alignment system having a target fixedly attachable to a wheel of the vehicle and a camera for viewing the target and capturing image data of the target, the determination comprising:
