AUGMENTED REALITY APPARATUS

An embodiment of the invention relates to an apparatus and related methods for providing a person with an augmented reality, the apparatus comprising: a projector that projects light that generates an augmenting visual image (AVI); optics that directs to a camera a portion of the projected light and a portion of light arriving from a scene so that a combined image comprising an image of the scene and the AVI are generated in a photosensor in the camera; and a controller that processes the combined image to compare positions of homologous features in the image of the scene with positions of corresponding location markers in the AVI, and renders an adjusted AVI based on the comparison, so that the location markers and the corresponding homologous features are substantially coincident in the combined image.
