摘要
狭缝光栅裸眼立体显示器是通过狭缝的遮挡效应来实现立体显示的,而串扰是决定其3D成像质量的关键因素,如何有效的分析其串扰进而减少串扰是立体显示研究一大课题。基于此目的,本文推导了狭缝光栅裸眼立体显示器中串扰的定量计算方法,并结合matlab对串扰进行了理论模拟,同时设计了基于USB摄像头的串扰测试方案,对设定的双视点后置夹缝光栅的串扰进行了实验测试,测试结果与理论模拟基本一致,其串扰度低于5%。实验结果表明此定量研究方法是可行的。
Auto-stereoscopic display can be realized with the aid of gratings, whose performance highly depends on crosstalk.There is a hot topic in the field of stereoscopic displaythat how to effectively analyze the crosstalk and reduce it. The paper derived formulae forquantitative calculation of crosstalk in grating base USB roug that d auto-stereoscopic display and then conceived a scheme for measurement of crosstalk based on a camera and with the help of matlab analyze. As the experiments show the measured crosstalk was in h agreement with the theoretical simulation, which was less than 5%. The experiments result show the method of quantitative research is workable.
