摘要
针对多投影面系统的曲面拼接问题,提出了一种视频实时处理方法,该方法首先通过Filter-Pipeline链路模型很好地在普通PC上实现了在保证视频流畅播放的条件下,对视频源进行实时处理;然后再进行保持边缘平滑的非线形几何校正和保持边缘亮度的均衡过滤(filter)。采用这一方式构架的系统不仅具有很强的灵活性,并且还能够在取得高质量场景效果的同时,大大降低构建成本,从而提高了系统的性价比。此外,通过F-P模型中filter的增加和修改,还可以很容易对系统的功能进行修改,并为系统的扩充提供了支持。
By using F-P（Filter-Pipeline） model, this paper proposed a way to stitch multi-projector displays in real-time video processing. The model takes muhithreading technology which can process several frames at the same time. It ensures that the video can be played fluently with a high quality effects. With this model, the system can be easily constructed based on the common PCs and benefits us with reduced cost. Furthermore, the system constructed with F-P model can adapt to a new environment with the extensibility to add or change the filters in the model. Here, this paper also gives two examples in designing ＂geometrical transform filter＂ and ＂edge smoothing filter＂ and approved to be well done in real-time video processing.
