| Popis: | This paper presents a novel algorithm for calibrating multiple casually placed projectors, via a single uncalibrated camera, to produce a "wallpaper" projection, which is equivalent to printing a single image onto a flat sheet of paper and pasting it to the screen. Based on a piecewise planar model, the method described here combines the advantages of global surface fitting and homographies to generate high accuracy geometric correction independent of the camera position and viewing angle. Experimental results validate the approach, achieving seamless displays with various multi-projector arrangements. The proposed calibration mechanism is applicable to both curved and planar screen surfaces and to single as well as multiple projector displays. |
