Abstract
Disclosed is an apparatus and method of tiling and stitching together multi-projector images. The projection system enhances brightness, enables polarization based stereoscopic imagery and matches brightness for all viewers that view the images from the projection system. The projection system includes two or more projectors and projects two dimension and three dimensional images onto projection screens, such as gain screens.
Claims20
A multi-projector system, comprising:
- a plurality of projectors configured to project imagery light, the plurality of projectors comprising:
- a first projector configured to project a first portion of a stitched image along a first light path;
- and
- a second projector configured to project a second portion of a stitched image along a second light path;
- and
- a first reflective element disposed in the first light path, wherein the first reflective element is configured to align the first light path relative to the second light path such that the stitched image comprises a transition region in which the first portion and second portion of the stitched image overlap, and imagery light from the first and second projectors within the transition zone have an angular deviation, theta, therebetween, ranging between about 0° to about 1°.

A multi-projector unit comprising:
- a housing;
- a plurality of projectors configured to project imagery light, the plurality of projectors comprising:
- a first projector disposed in the housing and configured to project a first portion of a stitched image along a first light path;
- and
- a second projector disposed in the housing and configured to project a second portion of a stitched image along a second light path;
- and
- a first reflective element disposed in the first light path, wherein the first reflective element is configured to align the first light path relative to the second light path such that the stitched image comprises a transition region in which the first portion and second portion of the stitched image overlap;
- wherein the housing is configured with predetermined clearance for a plurality of alignments of the first and second light paths.

A multi-projector display system comprising:
- a gain screen;
- a plurality of projectors configured to project imagery light to the gain screen, the plurality of projectors comprising:
- a first projector configured to project a first portion of a stitched image along a first light path;
- and
- a second projector configured to project a second portion of a stitched image along a second light path;
- and
- a reflective element disposed in the first light path, wherein the reflective element are configured to align the first light path relative to the second light path such that such that the stitched image comprises a transition region in which the first portion and second portion of the stitched image overlap, and a gradient within the transition region is less than a just noticeable difference (JND).
