摘要
提出了一种3D字幕的混合插入方法,即插入的字幕既能产生立体效果,又能融入到真实的场景中。将字幕以一定的负视差分别添加到左右视图中,并根据场景的深度情况来确认景物与3D字幕的遮挡关系,解决3D图像中字幕与图像深度混乱的问题,让字幕与场景虚实结合,能达到更真实的立体观看效果。
In this paper, a solution for inserting 3D subtitles in a 3D video is presented. This subtitles could not only produce three-dimensional effect, but also be introduced in a real situation. Author inserts subtitles in left and right images with a certain negative parallax, and confirms the occlusion between subtitles and object according to their depth information to override their depth cue conflicts. Aligning 3D subtitles and real objects could achieve high quality stereo effect.
