1. A method for presenting observable indicia on a surface within a vehicle service bay during a vehicle service procedure, comprising:
- establishing a three-dimensional spatial frame of reference, said spatial frame of reference encompassing at least a portion of said surface within the vehicle service area;
determining at least one parameter associated with a vehicle disposed within said spatial frame of reference; and
projecting observable indicia onto said surface at a selected position within said spatial frame of reference, said selected position related to said at least one determined parameter.

Abstract
A vehicle service system and method to determine spatial parameters of a vehicle, employing a display system under processor control, to display or project visible indicia onto surfaces in proximity to a vehicle undergoing a safety system service or inspection identifying one or more locations, relative to the determined vehicle centerline or thrust line, at which a calibration fixture, optical target, or simulated test drive imagery is visible for observation by a sensor onboard the vehicle.

12. A method for testing a vehicle on-board sensor system having a field of view external to the vehicle, comprising:
-
positioning a vehicle within a vehicle service bay with the field of view of the on-board sensor system encompassing an emitter system configured to emit electromagnetic energy at a frequency detectable by said vehicle on-board sensor system; and operating said emitter system to selectively emit said electromagnetic energy towards said vehicle, said emitted electromagnetic energy tuned to simulate movement of an object towards or away from said vehicle. - View Dependent Claims (13, 14, 15, 16, 17)

18. An improved vehicle service system having a set of sensors for acquiring data associated with a vehicle undergoing a service or inspection in a service area, a processor configured with software instructions to evaluate the acquired data and to identify at least a position of a feature of the vehicle within a spatial frame of reference, the improvement comprising:
-
an optical projection system having a projection axis and a field of projection encompassing at least a portion of said service area, said optical projection system operatively coupled to the processor; and wherein said processor is further configured with software instructions to control said optical projection system to project a visible indicia onto a surface within said service area, at a location which is relative to an identified position of said vehicle feature. - View Dependent Claims (19, 20)
