为使立体图像在3D显示时有更好的立体视觉效果和舒适度,提出一种针对立体图像水平视差的自适应调整方法来提高立体显示效果。通过特征点匹配获取拍摄场景的深度分布信息,提取最大深度和最小深度,结合当前的基线以及人眼可接受的最大视差和最小视差重新调整基线,直到获取合适的基线,从而保证拍摄场景在舒适立体成像区内成像。所提方法不会引起任何立体图像失真。为验证该方法对视差的控制效果,设计并完成了相应的实验。实验结果表明,该方法能够自适应调整视差,实现强烈的立体视觉效果。

To achieve good stereoscopic effect and avoid visual discomfort, an adaptive horizontal parallax adjusting method is presented for stereoscopic images. The depth information in a scene is extracted by feature point matching, obtaining the maximum and minimum depths. An appropriate baseline is obtained after the resetting of baseline based on the current baseline and the maximum and minimum parallaxes acceptable to the human eye, ensuring that the scences are imaged in a comfortable stereo imaging area. The proposed method does not introduce stereo image distortion. The control effect of the proposed method is verified by experiments. Experimental results show that the proposed method can adaptively adjust the parallax and realize strong stereoscopic effect.
