摘　　要：运用3D字幕视差与背景景深的对应关系,基于立体视觉的双目视差原理叠加3D字幕,实现了基于三维图像内容的景深叠加3D字幕的系统。该立体字幕叠加方法具有简单、稳健等特点,缓解了观看时的视觉疲劳问题,使观众更舒适地观看立体图像和字幕。In the paper, a system for overlaying stereoscopic subtitles has been realized based on the depth of stereoscopic image content, which is based on the principle of binocular disparity to overlay three - dimension subtitles by using the corresponding relation of 3D subtitles disparity and depth of field. This method for overlaying stereoscopic subtides is simple and robust, which will relieve problems like eye fatigue and motion sickness experienced by viewers. Viewers can read the stereo images and subtitles with ease and comfort.
