Abstract: A vehicle service system incorporating a pair of gimbal-mounted optical projection systems enables an operator to selectively orient each optical emitter of the optical projection system to illuminate a location on a vehicle surface in proximity to the system. Signals indicative of an orientation of each optical emitter about three-axes of rotation are received at a controller programmed with software instructions to utilize the received signals, together with known locations for the systems, to calculate a three-dimensional coordinate for the illuminated location within an established frame of reference. The controller is further programmed to utilize the calculated three-dimensional coordinate of the illuminated location as an origin point for determining one or more placement locations within the established frame of reference for ADAS sensor calibration or alignment targets.
