A wheel alignment system includes a side-to-side reference including an active reference pod and a passive reference pod disposed on opposite sides of the vehicle. The active reference pod includes a reference image sensor fixedly attached to a reference target, for mounting on a first side of the vehicle such that the reference image sensor produces image data including a perspective representation of the passive reference pod disposed on a second/opposite side of the vehicle. In operation, alignment cameras on the opposite sides of the vehicle capture perspective representations of targets mounted to vehicle wheels and of targets of the active and passive reference pods. A computer processes the image data to compute an alignment measurement of the vehicle based on a spatial relationship between the active reference pod and the passive reference pod determined according to the image data produced by the reference image sensor.

Vehicle wheel alignment methods and systems

A vehicle measurement system that provides highly realistic guidance to perform a vehicle measurement procedure is described. An exemplary system includes a data storage device configured to store vehicle data for a plurality of vehicles. The vehicle data corresponding to each respective vehicle includes an image of the vehicle and information of predefined points on the vehicle to which emitters or targets should be attached for performing a vehicle measurement procedure. A user interface is provided to receive a user input identifying a vehicle under test. After the user identifies a vehicle under test, the system retrieves vehicle data corresponding to the vehicle under test from the data storage device; and displays the image of the vehicle under test on the display with the predefined points on the vehicle identified.
