Abstract

In this paper, we have developed a human representation system we call “MulDiRoH.” It consists of a multiview display that uses a QDA screen and multiple cameras. The QDA screen has a large, wide viewing area that enables observers to comfortably watch the display. It is also convenient in that accurate projector orientation is unnecessary; this makes easy system construction possible. In this paper, we describe the MulDiRoH system and propose a “Tiled Image Method” to achieve shorter projection distance with it and a “Perspective Transform Method” to correct views obtained with it.
