我们提出了一种3D视频显示技术，允许多名观众在360度水平弧线上观察3D图像，而不需要戴3D眼镜。该技术使用圆柱形视差屏障和一维光源阵列。我们已经开发了一种使用这种技术的实验显示器，并演示了在不使用3D眼镜的情况下，从360度水平弧线上观察3D图像。由于这项技术是基于视差全景图的，视差数目和分辨率受到视差势垒处的衍射的限制。为了克服这些限制，我们通过旋转视差屏障来改进技术。我们在新的实验展示中采用了这项新技术。该显示器能够显示直径100 mm、高度128 mm的圆柱形3-D视频图像。图像以1254像素的圆形和128像素的垂直分辨率描述，并以30赫兹的频率刷新。每个像素的视角为60度，分为70个视图，因此每个像素的角视差间隔小于1度。在这种情况下，观察者可能几乎察觉不到离散视差。像素排列在圆柱面上，以允许从各个方向观察产生的3D图像。
We propose a 3-D video display technique that allows multiple viewers to observe 3-D images from a 360-degree horizontal arc without wearing 3-D glasses. This technique uses a cylindrical parallax barrier and a one-dimensional light source array. We have developed an experimental display using this technique and have demonstrated observation of 3-D images from a 360-degree horizontal arc without the use of 3-D glasses. Since this technique is based on the parallax panoramagram, the parallax number and resolution are limited by the diffraction at the parallax barrier. To overcome these limits, we improved the technique by revolving the parallax barrier. We have incorporated this new technique in our new experimental display. The display is capable of displaying cylindrical 3-D video images within a diameter of 100 mm and a height of 128 mm. Images are described with a resolution of 1254 pixels circularly and 128 pixels vertically and are refreshed at 30 Hz. Each pixel has a viewing angle of 60 degrees that is divided into 70 views, so the angular parallax interval of each pixel is less than 1 degree. In such a case, observers may barely perceive discrete parallax. The pixels are arranged on a cylindrical surface to allow the produced 3-D images to be observed from all directions.
