| description | Systems, methods and apparatus to continuously calibrate images displayed on a screen or surface by one or more projection devices during display of the images are disclosed. The systems, methods and apparatus comprise defining a plurality of fiducial markers on the screen, detecting, by a registration device, such as a camera, the plurality of fiducial markers in an image of the screen, adding a plurality of reference markers to an image displayed on the screen, detecting, by the registration device, the plurality of reference markers in the displayed image, determining a mapping between positions of the reference markers on the screen to positions of the reference markers in the displayed images, calculating an image warp based on the mapping and a layout of the images to be displayed and applying the image warp to images from an image generator to produce geometrically corrected images for display on the screen. |
