摘要
在嵌入式环境下设计开发了一套基于USB摄像头的视频监控系统。系统通过V4L接口从USB摄像头采集图像,借助QT图形库实现视频播放;通过OSS接口实现音频数据的采集与播放;同时能将音视频信息录制成通用的AVI格式文件保存到U盘中。实验表明系统的设计方案和实现技术是可行的。
A video monitoring system was designed and developed based on USB camera in embedded environment. In the system, pic- tures are captured from USB camera through V4L API and displayed on LCD by QT; Sound data is captured and played through OSS API; in addition, video and sound data can be record on USB disk as AVI files. Experiment shows that the design and implement teleology of the system are feasible.
