为了表征狭缝光栅自由立体显示器存在的左右眼视差图像的混叠程度,提出了立体图像串扰度C的概念。根据狭缝光栅自由立体显示器的结构和工作原理,应用几何光学知识,分析得出了立体图像串扰度C的计算公式,并给出了一个具体的狭缝光栅自由立体显示器的计算结果。通过观看实验,证明了所定义的立体图像串扰度C可以定量描述观看者在立体可视区域看到的立体图像的串扰程度。
In order to characterize the degree of aliasing of the left and right eye parallax images existing in a slit grating autostereoscopic display, a concept of stereoscopic image crosstalk C is proposed. According to the structure and working principle of the slit grating autostereoscopic display, the calculation formula of the crosstalk C of the stereo image is obtained by applying the knowledge of geometrical optics, and the calculation result of a specific slit grating autostereoscopic display is given. By viewing the experiment, it is proved that the defined stereo image crosstalk C can quantitatively describe the degree of crosstalk of the stereo image seen by the viewer in the stereoscopic visual area.
