摘要
为了设计一种在传输速率和易用性方面都满足要求的图像采集卡,设计了一种基于USB2.0的实时高速图像采集系统,该采集系统符合USB2.0标准,采用专用的二值化电路,以CPLD实现传输控制,ISP1581作为USB总线控制器,有效地解决了图像数据的二值化、传输和存储,为实时图像处理提供了方便.主要讨论了该系统的实现原理、硬件结构设计和软件设计,并且给出了相应的测试数据和运行结果,试验证明该图像采集系统满足高速、实时图像采集.
A real-time and high speed image collection system based on USB 2.0 is designed and implemented in this paper. The principle of this system, the hardware structure, the software scheme, and the testing results are discussed here. It has been proved that this system could meet the requirements of real-time and high speed image collection. In this system, ISP1581 is used as USB bus controller and data transmission is performed by CPLD. This method not only resolves data transmission and storage effectively, but also makes real-time image processing conveniently.
