Calibration of a multi-projector system for display on a cylindrical surface

In this paper we present a method for geometrically, photometrically & colorimetrically calibrating a multi-projector system for display on a cylindrical surface. Using a single camera we reconstruct the 3D surface of the display and determine the projector-screen relationship to accurately register projected images. Given these relationships, we apply chrominance gamut morphing in the overlap regions to smoothly transition from one projected image to the next. After white point balancing and perceptual brightness constraining, the final registered and blended images are shown by each respective projector to create a seamless high resolution image.
