摘　　要：为了显示可以裸眼周视观看和具有悬浮特性且可触摸的立体图像,通过分析多种立体显示技术原理、应用范围及其优缺点,提出了一种新型的立体显示技术。电机带动定向屏旋转,将多投影机出瞳成像并形成空间的观察域,当观察者双眼位于观察域内时,无需佩戴眼镜即可观察到具有运动视差的立体图像,且此图像具有悬浮可触摸的效果。对系统中的关键技术进行了阐述,通过实验得到了观察距离为580mm、悬浮中心高度为150mm的立体图像。In order to display the stereoscopic images which can be observed in 360-degree and glasses-free, and through analyzing the basic principles, application fields, advantages and disadvantages of the 3D display technologies, a new type of stereoscopic display technology is presented. Rotating directional screen driving by motor can image the exit pupils of the multi projectors and form the spatial view zone. Observers who have their eyes placed in the view zone can have the 3D images which have motion parallax and the effect of suspension and tangibility. And the images can be observed by glasses-free. The key technologies of the display system are elaborated, and through experiments, the stereoscopic images are obtained whose observation distance is 580mm and suspension center height is 150mm.
