摘　　要：本文介绍了一种实用的基于通用串行总线(USB2.0)的高分辨率(640×480以上)、快速(24帧/秒以上)数字图像实时采集和传输系统的设计,其中包括图像采集卡的硬件结构以及主机上基于MFC的应用软件开发。该系统采集的静态图像分辨率最高达到2048×1536,图像采集频率可达48MHz,能够实现640×480分辨率图像连续视频输出。该系统有效地解决了图像数据的实时传输和存储,为全数字图像的实时处理提供了方便。The paper introduced a kind of practical system based on universal serial bus（ USB2.0） to realize the acquisition and transmission of digital images of high resolution （above 640×480） at more than 24 frames/s rate, including the hardware frame of image acquisition circuit board and the development of software on host PC based on MFC. The system characteristics include the max image resolution which is 2048×1536, the video frequency exportation of the continuous 640 × 480 pictures and the 48 MHz image acquisition frequency. It resolves real-time transferring and storing of image data effectively and provides convenience for real-time image signal processing.
