摘　　要：为实现清分机对纸币图像快速准确地采集,提出了一种基于FPGA的图像采集系统设计。系统由CIS采集模块、A/D转换模块和FPGA与DSP之间数据传输缓存模块组成。讨论了采集系统的结构和FPGA对于各模块的逻辑控制过程。这种设计具有功能集成、实现简单和修改方便等优点,能得到满意的图像结果。In order to achieve rapid and accurate acquisition of paper currency images by sorter, an image acquisition system based on FPGA is designed. This system consists of acquisition based on CIS module, analogto-digital converter module and FIFO module for image cache. The structure of the system and the logic control process of FPGA are discussed.This design has the advantages of simple implementation and easy modification, and the results are satisfied.
