Summary:To provide a space screen system, a space screen, and a stereoscopic display method that can achieve naked eye stereoscopic vision easily at an inexpensive price.SOLUTION: A 3-D model being an object of projection is stored in advance, in a memory of a projection unit 1, as predetermined arbitrary number of sliced images toward the back (or the front) in a projection direction. A control unit of the projection unit 1 or another PC creates corrected sliced images obtained by performing curve correction according to a curved surface of a screen 2 and stores the images in the memory of the projection unit 1. A rotation drive unit 3 rotates the screen 2 at a high speed. The projector unit 1 continuously outputs the corrected sliced images or sliced images being image data obtained by cutting the 3-D model into round slices toward the back (or the front). Thus, different images are localized toward the back or the front and are switched at a high speed, and the resolution of the eyes cannot catch up with the speed, and thereby the images look like a stereoscopic image.SELECTED DRAWING: Figure 1 【課題】裸眼立体視を、簡単で安価に実現することができる空間スクリーンシステム、空間スクリーン、立体表示方法。【解決手段】投影対象である3Dモデルは、投影方向の奥(又は手前)に向かって予め定められた任意の枚数スライスした画像を予めプロジェクター部1のメモリに記憶しておく。プロジェクター部1の制御部又は他のPCにより、スクリーン2の曲面に応じて湾曲補正した補正スライス画像を作成し、プロジェクター部1のメモリに記憶する。スクリーン2を回転駆動部3で高速回転させる。そこに、3Dモデルを奥に向かって(又は、手前に向かって)輪切りにした画像データである補正スライス画像又はスライス画像を、プロジェクター部1で連続的に出力する。これにより、奥に又は手前向かって異なる画像が定位され、それが高速で切り替わるため、目の解像能が追いつかず立体に見える仕組みである。【選択図】図1
