| 摘 要： | 以立体视频左右放置合成算法为核心算法,使用DDRSDRAM作为帧同步缓冲器件,采用FPGA作为平台,实现了一套立体视频合成系统。该系统降低了因制作立体视频需要处理两路带视差的视频而带来的对额外传输带宽和编解码器的需求,合成视频具有实时性好、失真小、立体感良好等特点。

| Abstract: | A system based on FPGA capable of synthesizing stereoscopic 3D video comply with the side-by-side synthesis algorithmi is proposed, using DDRSDRAM as a buffer for frame synchronization. The system can successfully reduce the demand of transmission bandwidth and codec in making 3D video. The real-time synthesis video possesses character of little distortion and the 3D viewing is good. |
