Abstract
An apparatus includes a first camera configured to capture a first image being displayed, a second camera configured to capture a second image being displayed, and a processor configured to generate a pair-wise homography transform for the first camera and the second camera, and map, based on the pair-wise homography transform, the second image from a second frame of reference of the second camera to a first frame of reference of the first camera. The processor is further configured to determine a first corrected quadrilateral for the first image and a second corrected quadrilateral for the second image in the first frame of reference, and project, based on the pair-wise homography transform, the second corrected quadrilateral from the first frame of reference to the second frame of reference. The quadrilaterals are then processed to warp respective images for geometric correction before projecting the images by respective projectors.
