柱透镜光栅立体显示的串扰度

为实现对柱透镜光栅立体显示串扰的定量分析,提出了一种串扰度的计算方法.首先,创建了用于描述显示屏上子像素视差图像的视点矩阵.然后,基于几何光学并结合视点矩阵,创建了用于描述观看位置上观看到的各幅视差图像信息量的视区矩阵.最后,由视区矩阵推导出串扰度的计算公式.实验测量结果与计算结果相近.验证了该计算方法的有效性.该方法可用于分析光栅倾斜角度、视点数及观看位置等因素对串扰的影响,且在定义串扰度阈值的基础上可确定最佳立体观看区域.

Crosstalk Ratio of the Lenticular-lens-based Autostereoscopic Display

In order to realize the quantitative analysis of the crosstalk in the lenticular-lens-based autostereoscopic display,a crosstalk ratio calculation method is proposed.Firstly,a viewing point matrix is created.Values of the matrix represent that the corresponding parallax images are filled to the subpixels in the screen.Secondly,based on the geometrical optics and the viewing point matrix,a viewing zone matrix is obtained.Values of the matrix represent the amount of information of each parallax image.Finally,the crosstalk ratio calculation formula is deduced.The proposed calculation method is proved by the experiment.It can be used to analyze the affects of the factors,such as the tilt angle of lenticular lens,the view number,and the viewing position,on the crosstalk.And once the crosstalk ratio threshold is defined,the optimal viewing zone can be determined.
