摘　　要：随着数字视频和新型显示技术的飞速发展,3D电视取代传统2D电视成为主流趋势。通过多摄像机阵列拍摄同一场景,并将各路视频图像校正、融合,然后输入到裸眼3D电视可以产生非常震撼的3D观看效果。当观看者改变观看角度时,还可以进行视点间的切换,因此观看三维电视比传统二维电视的沉浸感更强。通过人手工放置的平行多摄像机阵列拍摄出来的图像会产生垂直视差,观看存在垂直视差的立体图像会产生不适感,因此必须进行多视点图像校正。本文提出一种简单有效的多视点图像校正算法,有效消除垂直视差,可以达到实际应用的要求。with the rapid development of digital video and new display technology,3 D TV instead of traditional 2D TV has become the main trend. Through the multi camera array shooting the same scene, and the various video image correction, fusion, and then enter the naked eye 3D TV can produce a very shocking 3D viewing effect. When the viewer changes the viewing angle, it can also switch between views, so watching three-dimensional TV is better than the traditional two- dimensional TV immersion. The images produced by the parallel multi camera array placed by hand can produce the vertical parallax, and the stereo image of the vertical parallax can cause dis- comfort. In this paper, a simple and effective algorithm for multi view image correction is proposed, which can effectively eliminate the vertical parallax.
