Abstract
When a 3D display system is used for remote manipulation, the special glasses for looking at the 3 D-image disturb the manipulation. So auto-stereoscopic display is preferable for remote manipulation work. However, the eye position area of the auto-stereoscopic display which shows the 3D-image is generally narrow. We constructed a 3D display system which solved these problems. In the system, 1.stereoscopic images displayed on the special LCD are projected on a large concave mirror by a projection lens. 2.The viewing-zone limiting aperture is set between the projection lens and the concave mirror. 3. The real image of the aperture plane is made at a certain position in vacant space by the concave mirror, and the image position is the viewing zone. By putting both eyes at the position and looking at the concave mirror plane, the observer can see the stereoscopic image without glasses. To expand the area at which the observer can observe the 3D-image, we proposed and constructed the system of the eye-position tracking of the viewing zone by detecting the eye-position of the observer. An observer can not only move horizontally and vertically by rotating the concave mirror, but also move to front and back by moving the viewing zone limiting aperture in the system.
