In this paper, we present a polyhedron-shaped floating autostereoscopic display viewable from 360 degrees using integral photography (IP) and multiple semitransparent mirrors. IP combined with polyhedron-shaped multiple semitransparent mirrors is used to achieve a 360 degree viewable floating three-dimensional (3D) autostereoscopic display, having the advantage of being able to be viewed by several observers from various viewpoints simultaneously. IP is adopted to generate a 3D autostereoscopic image with full parallax property. Multiple semitransparent mirrors reflect corresponding IP images, and the reflected IP images are situated around the center of the polyhedron-shaped display device for producing the floating display. The spatial reflected IP images reconstruct a floating autostereoscopic image viewable from 360 degrees. We manufactured two prototypes for producing such displays and performed two sets of experiments to evaluate the feasibility of the method described above. The results of our experiments showed that our approach can achieve a floating autostereoscopic display viewable from surrounding area. Moreover, it is shown the proposed method is feasible to facilitate the continuous viewpoint of a whole 360 degree display without flipping.
在本文中，我们展示了一种使用积分摄影（IP）和多个半透明镜的360度可视的多面体形状的浮动自动立体显示器。IP与多面体形状的多个半透明镜相结合，用于实现360度可视的浮动三维（3D）自动立体显示器，其优点是能够被多个观察者从不同视角同时观看。采用IP来生成具有全视差特性的3D自动立体图像。多个半透明镜反射相应的IP图像，并且反射的IP图像位于多面体形状的显示设备中心周围，以产生浮动显示。空间反射的IP图像重建出一个360度可视的浮动自动立体图像。我们制造了两个用于生产此类显示器的原型，并进行了两组实验来评估上述方法的可行性。我们的实验结果表明，我们的方法可以实现从周围区域可视的浮动自动立体显示。此外，结果表明所提出的方法对于促进整个360度显示器的连续视角而无需翻转是可行的。
