視覚サーボを用いた移動・変形するスクリーンへの投影画像制御

抄録

In this paper, we propose a new display system consisting of a high-speed vision and high-speed projector, which has remarkable features. First of all, this system generates projection images using simple image processing, because the projection image is controlled without three dimensional shape of an object. Secondary, in this system the projection image is controlled based on errors on the image plane with visual servoing techniques. By using this technique, this system can project images regardless of the pose of the object to be projected. Moreover, there is no need for precise calibration between the projector and camera. The last feature is that it utilizes high-speed vision. This feature makes it possible to control projected image in real time. Having these features, our proposed display system can project images not only on stable fixed screen but also on other objects such as deformable screens and moving screens. To validate the proposed system, we experimented by projecting on a moving screen as well as a bending screen.
