Multi perspective panoramic imaging

摘要

Panoramic images have only been feasible if all contributing image patches share a common center of projection. Then, they can be consolidated into a single image using perspective transforms. In contrast to that, we propose a novel non-linear warping scheme which allows the merging of multi-perspective images, thus taking advantage of scattered cameras. Therefore, a polygonal cut is defined in two source images to be merged. Usually, the layout of the cuts does not allow a user to stitch both images together naively. Thus, two convex combinations of a warped and a canonic coordinate system are applied so that both source images fit together at the cutting edge while the inevitable distortion decreases towards the borders of the image to obtain a natural appearance.
