【摘要】 针对偏振式微型三维(3D)投影系统,研究了其主要性能参数———串扰对立体再现质量的影响。搭建了串扰测量平台,分别对偏振式立体投影仪、金属屏幕以及偏振眼镜3部分带来的串扰进行了测量及分析,得出3部分的串扰大小依次递减。分析结果表明,偏振式立体投影仪在减小串扰方面有待进一步提高,并印证了在立体显示中金属屏幕性能对系统再现质量起着决定性作用。本文为偏振式微型3D投影系统再现质量好坏的评价提供了性能参数及量化指标,也为偏振式立体投影仪性能参数研究及测量提供了方法。更多还原

【Abstract】 Polarized mini-three-dimensional projection system is mainly composed of a polarized mini-three-dimensional projector,a metal screen and polarized glasses.Aiming at this system,the impact of crosstalk on the quality of stereoscopic display is investigated.Then a crosstalk measuring system is implemented.In this paper,we measure and analyze the crosstalk induced by the polarized three-dimensional projector,the metal screen and the polarized glasses.The results show that the values of crosstalk caused by the three parts are in a descending order.It can be concluded that the quality of the polarized stereoscopic projector should be further improved,and the quality of the metal screen plays a decisive role in the mini-3D projection system.The research in this paper provides the performance parameters and quantitative indicators for the evaluation of mini-3D projection system,and a method for measuring the polarized stereoscopic projector performance parameters.更多还原
