Abstract
A non-contact sensor for determining orientation of an object, such as a tire and wheel assembly of a vehicle, includes a projector assembly having a light emitter, a lens assembly and a mask, with the mask including mask apertures and the light emitter configured to project light through the lens assembly and mask apertures and onto the object, and with the mask apertures creating a light pattern of projected light onto the object. The sensor also includes an imager configured to image reflections of the light pattern from the object, and a processor. The projector assembly and imager are angled with respect to one another, and the processor is configured to process imaged reflections of the light pattern to derive the orientation of the object, such as the alignment orientation of the tire and wheel assembly.
