Zusammenfassung:
We present a hardware-accelerated method for video-based rendering relying on
an approximate model of scene geometry. Our goal is to render high-quality
views of the scene from arbitrary viewpoints in real-time, using as input
synchronized video-streams from only a small number of calibrated cameras
distributed around the scene. Despite the fact that only a very coarse geometry
reconstruction is possible, our rendering approach based on textured billboards
preserves the details present in the source images. By exploiting
multi-texturing and blending facilities
of modern graphics cards, we achieve real-time frame-rates on current
off-the-shelf hardware. One of the possible applications of our algorithm is to
use it in an inexpensive system to display 3D-videos, which the user can watch
from an interactively chosen viewpoint, or ultimately even live 3D-television.
