摘　　要：随着立体拍摄设备的普及,立体影视的后期稳像需求大大增加。直接观看带有抖动的立体视频,极易造成视觉疲劳。利用传统2D稳像方法分别稳像合成的立体视频很可能引入新的垂直视差,并且会导致水平视差的不稳定,大大影响视觉体验。因此,提出了一种改进的立体视频稳像方法,在3D运动模型进行单目稳像的基础上,增强两路视频的时空一致性约束,更好地稳定水平视差及消除垂直视差。最后对稳定后的序列进行合理的裁切放大。对几组不同的立体抖动视频进行了试验,测试结果表明所提出的方法是有效的。With the prevalence of stereo shooting equipment, there is an increasing need for stereoscopic video stabilization. Directly watching stereoscopic videos with jitter will easily generate visual fatigue. If traditional 2D video stabilization method is applied independently to left and right videos, additional vertical parallax will be introduced and horizontal parallax will become unsteady, which will lead to bad viewing experience. Therefore, an improved stereoscopic video stabilization method based on 3D-modeled monocular image stabilization is presented, strengthening spatial-temporal consistency constraint to stable horizontal parallax and minimize vertical parallax more effectively. Finally, the video sequences are cropped and enlarged properly. Several different shaky stereoscopic videos have been tested, and the results show that the method is effective.
