摘要

针对偏振式立体投影仪

研究了其左右光路不一致性及立体串扰度对立体投影质量的影响。屏幕上投影图像的不严格重合、两路光路在色度亮度上的差异以及偏振眼镜造成的立体串扰等都会影响最终的立体投影质量。提出用上述参数评价偏振式立体投影仪的立体投影质量并完成了评价系统的搭建。通过数字摄像头获取立体投影设备在屏幕上相应的投影图像

采用OpenCV等算法计算及分析了上述参数值

并将该值与预存的最大偏差值比较后进行显示及反馈。在一台偏振式立体投影仪上进行了系统验证

结果表明该系统能够有效地对立体投影仪性能参数进行测量及反馈

有利于全面分析偏振式立体投影仪的立体投影质量

便于提高投影仪的整体质量。

Abstract

For polarized stereoscopic projector

the influence of two main performance para-meters

which are the inconsistency in color and brightness of the left and right optical paths and stereo crosstalk

on stereoscopic projection quality is studied. The stereoscopic projection quality will be influenced by a number of factors

which are two projection images not strictly coincident on the screen

two optical paths' difference in color and brightness

stereo crosstalk caused by the polarized glasses

etc. The evaluation method is presented to evaluate the stereoscopic projection quality according to those factors and the evaluation system is built. The system obtains projection images by a digital camera

those parameters were analyzed and calculated by OpenCV

and then were compared with the presented maximum deviation value

the comparison result were sent to display and feedback signal. The system function is verified by using a stereoscopic projector. The result indicates that the evaluation system can measure and feedback performance parameters of stereoscopic projector effectively

and help to analyze the stereoscopic projection quality of the polarized stereoscopic projector comprehensively

thus enhance the stereoscopic projection quality.
