摘　　要：针对目前银行网络化工作的需要,为提高银行工作效率,设计了一种基于定点DSP处理器及CIS(contact image sensor,接触式图像传感器)的纸币面额识别系统。该系统采用两个CIS模块测量钞票长度,DSP用于系统控制及图像处理,设计灵活,可实现不同版本不同面值钞票的混点,同时具有低成本、低功耗、高性能、智能化等优点。实验表明用该系统进行识别有很高的准确率。Face amount identification system is a practical system. A DSP and CIS based system is introduced to improve the efficiency. In this system the data acquisition is done by 2 CIS modules and DSP is used for control and data processing. And it can identify mixed banknote and different edition. This system is a low cost, low power consumption system with high performance as it＇ s based on DSP and CIS. The experiments indicate that the system has a very high accuracy rate.
