摘要
研究多视点裸眼立体显示视区变换, 提出一种利用压缩视点间距提高立体显示运动视差连续性的方法, 实现只需人眼微小的空间位移就可获得立体图像的更换。以四视点柱面透镜光栅裸眼立体显示为例, 对成像原理进行了研究, 推导出视点间距压缩后立体显示系统各个参数之间的关系, 并重点分析了立体显示视区的周期性特征。采用TracePro光学软件进行仿真论证, 结果表明, 通过压缩视点间距, 在没有引入新串扰度分量的前提下, 可有效提高立体显示视点的连续性。
Abstract
The change of stereo viewing zone was studied, a method to improve the continuity of motion parallax by reducing the spacing of viewpoint was proposed. A four viewpoints autosteroscopic display system with cylindrical lens grating was demonstrated, the imaging principle of lenticular sheet was studied, the parameter of the system was deduced, and the view points′ periodicity is analyzed. The imaging process was simulate and validated using TracePro, the results show that, the continuity of the adjacent view points can be effectly improved by reducing the viewpoint spacing, without inducing new crosstalk. Using this method, one can obtains different binocular images more continuously by shifting less spacial distance.
