摘要
人眼能获得立体视觉的根本原因是存在视差。利用柱面光栅能使投影成像在有限区域的特点,可以使人的双眼在同一时间分别看到不同的图像形成视差,从而获得立体视觉。本文提出一种双柱面结构的大屏幕自由立体背投系统,从理论上对其结构和成像原理进行了详细分析,并给出了计算机仿真结果。
Due to the existence of parallax,the human beings are created with an ability to achieve 3-D vision。Lenticular is capable of making the images from projectors be limited in a finite area, by virtue of this characteristic, the eyes are enabled to see different pictures simultaneously,simply we can call this phenomenon parallax, then before us, the 3-D vision appears. This paper puts forward a large screen, auto-stereoscopic projector system with a structure of double lenticular, and in theory, a detailed analysis of the model is provided to verify its availability, based on this, the results of computer simulation are also included.
