Patent ID: 8777418

Claim:
A projection and calibration system comprising: an image generator; a plurality of projectors for receiving an image from said image generator and projecting said image onto a screen to provide a final projected image, each of said plurality of projectors comprising a warping system enabled for geometry manipulation of images from said image generator; and a computer for performing a calibration process, said calibration process including comparing an uncorrected image projected by said plurality of projectors with a static geometrically correct image, where the static geometrically correct image is independent of any captured data by a camera, and generating calibration data for mapping said uncorrected image onto said static geometrically correct image, wherein said generating said calibration data comprises: projecting, via said plurality of projectors, a matrix of projected reference markers onto said screen; capturing, via the camera, a screen image of said matrix of projected reference markers; comparing locations of said projected reference markers with target reference marker locations stored in said computer as said static geometrically correct image; calculating new estimated locations for said projected reference markers; and iteratively repeating said projecting, said capturing, said comparing and said calculating steps until said projected reference markers are located within a predetermined distance of said target reference marker locations, and wherein each of said plurality of projectors maps incoming pixel locations from said image generator to corrected pixel locations in said final projected image based on said calibration data such that image warping occurs within each of said plurality of projectors.
