We describe a tiled-projection display system whose entire image is composed of twenty four patches of projection, sixteen of which are used for front projection and eight for rear projection on the center area of the screen. We use eight pairs of projectors to project the stereoscopic images, the left-eye image, and the right-eye image. The screen consists of differently shaped surface elements that are the partial surfaces of objects such as planes, spheres, cylinders, and tori. The following three technologies were developed for the display system: (1) a digital camera based measurement of the position and color features of the pixels projected on the screen, (2) software to compute the geometry correction and color modulation for edge blending by using the measurement data, and (3) real time image processing hardware to enable arbitrary geometrical warping and color modulation for individual pixels.
