摘要
传统的多路视频采集系统需采用专用的视频采集卡,采用专用的采集设备,由于其价格昂贵,且多由接口方式提供数据,后期合成处理的速度相对较慢,因此提出了基于DShow的多路视频实时采集合成处理系统,该系统使用普通的USB摄像头,配合微软的DShow,能够实时采集处理视频,能有效地用于监控,视频数据处理等地方。
The traditional multi-channel video capture system requires the use of a dedicated video capture card,with a dedicated capture device,because of its high expense and most data are provided by the interface,post-synthesis processing is relatively slow.So the real-time multi-channel video acquisition and processing system base on DirectShow is proposed.The system uses ordinary USB camera,with Microsoft＇s DShow,acquisition and processing video in real time.It can be used in monitoring,video data processing and other places.
