In this paper, we present the first method to geometrically register multiple projectors on a swept surface (e.g. a truncated dome) using a single uncalibrated camera without using any physical markers on the surface. Our method can even handle non-linear distortion in projectors common in compact setups where a short throw lens is mounted on each projector. Further, when the whole swept surface is not visible from a single camera view, we can register the projectors using multiple pan and tilted views of the same camera. Thus, our method scales well with different size and resolution of the display. Since we recover the 3D shape of the display, we can achieve registration that is correct from any arbitrary viewpoint appropriate for head-tracked single-user virtual reality systems. We can also achieve wallpapered registration more appropriate for multi-user collaborative explorations. Our method achieves sub-pixel accuracy and the image correction required to achieve the registration runs in real-time on the GPU. Swept surfaces are much more immersive than popular display shapes like planes, cylinders and CAVES. Our method opens up the possibility of using such immersive swept surfaces to create more immersive VR systems without compromising the simplicity of having a completely automated registration technique. |
