ライブビデオと3次元実環境モデルを用いた遠隔協調作業支援システム(「バーチャルVR～VR技術の応用・転用・新展開」特集)

抄録

In this paper, we propose a novel tele-presence system for collaborative work. Our tele-presence technique has advantages of both model-based and image-based approaches. In the technique, a virtual environment representing a remote place is presented by using projection texture mapping of live video images captured by a wearable camera onto a 3D geometry of the place acquired in advance. The virtual environment can be rendered from an arbitrary viewpoint, while its texture is dynamically updated according to the camera motion. The observer can then observe the remote place in cooperation with the remote worker. A feasibility study is also given which subjectively confirmed the effectiveness of the remote instruction mechanism.
