Abstract

A display system. A display device has viewports emitting expanded views of an image, an image receiving area receives the image, and optical conduits with exit pupil expanders expand the image through the viewports. A separate tracking projector has an image projector that projects an image along an axis, a marker search illuminator that projects light into a space including the axis, and an image capture component that captures target images that including at least three reflective marker images associated with the image receiving area. An image processor determines, based the marker images, a distance and an orientation of the image receiving area. A projection controller adjusts image data based upon the distance and the orientation to cause projected images to arrive squarely at the image receiving area.
