摘　　要：提出了一种基于CCD摄像头的自动立体显示器立体对比度和视区检测方法。首先,运用D irect3D API设计的计算机图形显示在自动立体显示屏上。然后,用一台CCD摄像头代替人的双眼接受立体视图。最后,根据算法提取数字图像的特征参数来计算说明自动立体显示器显示效果的立体对比度,并获得观看自动立体显示器的左右眼视区分布。实验结果表明,此方法能很好地检测自动立体显示器的立体对比度和左右眼视区。A method of inspecting stereo contrast ratio and view zones of autostereoscopic displays using CCD cams is proposed. Firstly, a designed computer graphics is displayed on the screen of autostereoscopic display. Secondly, one CCD cam, instead of the human two eyes, perceives the stereo image pair. Thirdly, the acquired digital images are processed. Finally, the feature parameters extracted from the images are used to calculate the separating degree that indicates the performance of autostereoscopic display. Experimental results demonstrate that the method proposed in this paper can well inspect the stereo contrast ratio and view zones of autostereoscopic display.
