摘　　要：本文设计了一种利用USB接口采集原始视频动态图像的系统的设计方法。这个系统采集的是未压缩的原始视频动态图像,可以把来自摄像机或电视的模拟信号转换成数字化的视频数据,再经USB接口送入计算机中。与常见的图像压缩采集卡相比,这个系统具有信息延迟小、图像清晰度高、安装使用方便的优点。系统硬件电路采用了方便的USB接口,一台计算机可以同时采集多路视频,方便后期进行图形分析、识别或比对处理。An acquisiton system of the original video dynamic image using USB interface is introduced. The system collects the original video dynamic image which is not compressed, and it can convert the analog signal which comes from the camera or TV to the digital video data, and then sends to the computer through the USB interface. Compared with the common image compression acquisition card, the system has the advantages of less information delay, high image clarity, convenient installation and use. The system hardware circuit uses a convenient USB interface,a computer can simultaneously collect the multi-channel video to facilitate the late graphics analysis, identification or comparison of processing.
