基于双目视差原理, 提出了一种新型的周视悬浮裸眼立体显示系统。采用菲涅尔透镜和单向散射屏实现了观察范围的纵向拓展, 形成的三维图像可周视观看, 有悬浮感且可触摸。对系统中采用的定向屏、旋转光阑、条状出瞳, 以及投影机的投影距离进行了分析和设计。经过实验验证, 立体图像合像舒适, 显示效果明显。

A new type of panoramic and suspending stereoscopic display system based on parallax principle is proposed. Fresnel lens and a one-dimensional scattering screen are used to expand the longitudinal range of view. The three-dimensional pictures displayed are panoramic, suspending, as well as tangible. The parameters of directional screen, rotating stop, stripe exit pupil and the projection distance of projector are analyzed. A panoramic and suspending stereoscopic display system is built to verify the validity of the system. The visual comfort of combined stereoscopic pictures and the display effect are both desirable.
