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。 Based on binocular parallax principle, a new type of peripheral naked eye stereo display system is proposed. Fresnel lens and one-way scattering screen to achieve the vertical extension of the observation range, the formation of the three-dimensional image can be seen from the week, with a sense of suspension and touch. The directional screen, rotating diaphragm, stripe exit pupil and projector projection distance were analyzed and designed in the system. After experimental verification, three-dimensional image co-ordination comfortable, showing obvious results.
