Tiled projection onto bent screens using multi-projectors

We provide a quick and efficient method to project a coherent image that is seamless and perspectively corrected from one particular viewpoint using an arbitrary number of projectors. The rationale is that wide-angle high-resolution cameras have become much more affordable than short-throw projectors, and only one such camera is sufficient for calibration. Our method is suitable for ad-hoc installations since no 3D reconstruction is required. We provide our method as open source solution, including a demonstrative client program for the Processing framework.
