摘要
介绍了基于CPLD的清分机纸币图像采集控制系统。采用接触式传感器(CIS)SV233A4W对高速运行的钞票进行图像采样,并将采样数据缓存到CPLD内部RAM中,为后续的DSP等图像处理模块提供数据。该系统扩展性强,只需修改内部相关程序就可满足不同应用要求,并可移植到其他图像采集系统。
This paper introduced the image acquisition control system of currency sorter based on CPLD.The system uses CIS SV233A4W to sample high-speed paper money,and store data to internal RAM of CPLD as a cache for image processing part such as DSP. The system has a good augmentability, can satisfy different requirements only by modifying the program. And it can be transplanted to other systems which need image acquisition.
