Abstract: A method of displaying a high-resolution image with a multi-projector display system. The method includes determining a luminance profile for each projector, receiving a high-resolution image frame representative of the high-resolution image, and generating for each projector a low-resolution sub-frame corresponding to the high-resolution image frame based on a geometric relationship between the projector and a reference coordinate system and on the luminance profile of the projector. The method includes simultaneously projecting each low-resolution sub-frame onto a target surface with the associated projector, wherein the projectors are configured such that the projected low-resolution sub-frames at least partially overlap on the target surface to form a projected image substantially equal to the high-resolution image.

Abstract: A color wheel assembly for use in a projector for stereoscopic imaging. The color wheel assembly includes a first portion able to polarize light in a first orientation and a second portion able to polarize light in a second orientation. The first and second portions allow the color wheel assembly, when in an image projector, to produce separate polarized images to achieve a stereoscopic image.

Abstract: In one aspect, a first sequence of patterns of light symbols that spatio-temporally encode two-dimensional position information in a first projection plane is projected onto a scene. A second sequence of patterns of light symbols that spatio-temporally encode two-dimensional position information in a second projection plane is projected onto the scene. Light patterns corresponding to the first and second sequences of patterns of light symbols reflected from the scene are captured at a capture plane. Captured light symbol sequence codes are determined from the captured light patterns. A correspondence mapping of the first projector plane and the second projector plane with respect to a reference coordinate system is generated based at least in part on correspondence between the captured light symbol sequence codes and the first and second sequences of light symbol patterns.
