3D Free-viewpoint video capturing interface by using bimanual operation

This paper proposes an interface for capturing the 3D free-viewpoint video of a soccer game by using bimanual operation. Users virtually capture 3D free-viewpoint video by observing a virtualized miniature soccer stadium on a tabletop. To exploit the human hand's dexterous manipulation ability, we use a 3D tracker to input the 3D position and the orientation of a virtual camera that captures the 3D free-viewpoint video. The proposed system displays the overhead-view on a tabletop where a user manipulates the virtual camera. By browsing this overhead-view, the context can be easily understood (e.g., positions of players and the ball) in a virtualized soccer scene. We develop a proposed system and conduct on evaluations to confirm the effectiveness of our proposed method.
