摘　　要：详细介绍了一种基于背投显示设备的裸眼立体显示方法,可实现观众在不佩戴特殊眼镜的情况下观看有立体效果的视频。不同于现在广泛采用的光栅方法,提出算法基于DLP特有的成像原理,更改原先的单片DMD投影为左右两片DMD交替投影,将对应于左右眼的视频帧按时间顺序交叉处理后,依次投射至屏幕上。和使用分光跟镜或者是采用光栅来分离左右眼接收光不同的是,提到的方法采用特殊的透镜屏幕,可以有效使得左右眼分别看到互不干扰的视频对,从而产生视差。实际观测效果证明方法在清晰度和观看视角方面都具有更优的性能,并且降低观看和视频源获取的复杂度。This paper proposes a novel method to realize naked-eye stereoscopic display based on DLP. The method we proposed is different from grating method used widely, it based on the DLP image-forming principle, two DMD chips are appllied instead of single DMD. The stereoscopic image pairs are intersected sequentially and projected to different orientation by each DMD. To separate the left and right video, lens is used and located before the screen.Left eye and right eye can receive corresponding frame individually. Some experimental results are given to demonstrate the proposed technology at last.
