【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。更多还原

【Abstract】 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 2 048×1 536, 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.更多还原
