Abstract
A calibration system including a display screen having a first surface and a second surface and a projector configured to project an image onto the first surface of the display screen and the image is viewable on the second surface of said display screen, wherein the projector includes a projector coordinate system. The calibration system also includes a camera configured to capture an image of an object through the display screen, where the camera comprises a camera coordinate system, and a calibration device configured to calibrate the display screen.
Claims19
A calibration system comprising:
- a display screen comprising a first surface and a second surface;
- a projector configured to project an image onto said first surface of the display screen and said image is viewable on said second surface of said display screen, wherein said projector comprises a projector coordinate system;
- a camera configured to capture an image of an object through said display screen, wherein said camera comprises a camera coordinate system;
- and
- a calibration device configured to calibrate said display screen.
A method for calibration, said method comprising:
- receiving a projector calibration image from a projector at a projector calibration device, wherein said prosector is configured to project an image onto a first surface of a display screen and said image is viewable on a second surface of said display screen;
- emitting light from a camera calibration device towards a camera, wherein said camera is configured to capture an image through said display screen;
- and
- calibrating said display screen based at least on said received projector calibration image and said emitted light.
A calibration system comprising:
- a projector configured to project an image onto a first surface of a display screen and a calibration surface, wherein said projector comprises a projector coordinate system, and wherein said image projected onto said first surface of said display screen is viewable on a second surface of said display screen;
- and
- a camera configured to capture said image through said display screen and on said calibration surface such that a camera coordinate system and said projector coordinate system are calibrated.
