Collimated stereo display system

1. A system comprising:

a processor;

an image generator configured to provide a stream of stereoscopic images comprising left eye images and right eye images;

a projector comprising at least one image modulator configured to receive the stream of stereoscopic images from the image generator and form light into the stereoscopic images;

a viewing apparatus configured to filter the light into the left eye images and the right eye images respectively thereby providing a three dimensional rendering of the stereoscopic images when viewed through the viewing apparatus;

collimation apparatus configured to receive and collimate the light from the at least one image modulator, such that rays of light are substantially parallel when the stereoscopic images are received at the viewing apparatus; and,

a curved surface, the stereoscopic images projected onto the curved surface for viewing and the processor is configured to adjust the stereoscopic images based on: a geometry of the curved surface and motion parallax cues based on a position of a viewer, the collimation apparatus comprising a collimating mirror configured to reflect the light from the curved surface such that reflected light is collimated and both accommodation and vergence cues in the stereoscopic images are generally in sync, the motion parallax cues taking the place of the vergence cues when head movement of the viewer is detected, so that objects in the stereoscopic images are pushed further away by the collimating mirror and infinity in the stereoscopic images looks like a real infinity out a window using the viewing apparatus, with eyes of the viewer relaxed both in vergence and focus.

2. The system of claim 1 , further comprising:

head tracking apparatus configured to acquire a position of the viewing apparatus; and

the processor further configured to adjust the stereoscopic images for viewing based on one or more of the position and the orientation of the viewing apparatus.

3. The system of claim 1 , further comprising a memory for storing data indicative of the geometry.

4. The system of claim 1 , wherein the processor is further configured to adjust the stereoscopic images based on the geometry of the curved surface by:

determining images for display, the images comprising the stereoscopic images when they are to be provided on a flat screen;

determining a distortion of the flat screen based on the data indicative of the geometry of the curved surface and the position of the viewing apparatus; and

adjusting the images based on the distortion such that the stereoscopic images will appear undistorted when projected onto the curved surface.

5. The system of claim 4 , wherein adjusting the stereoscopic images is repeated each time a change in position of the viewing apparatus is determined.
