摘要:
纸币图像实时采集是纸币清分系统自动化工作的首要任务.利用现场可编程门阵列并行控制技术,实现了纸币图像光电转换、模数转换、数据缓存等功能,为纸币清分系统实现真伪辨别、纸币分类、残币识别、冠字号提取等功能提供实时清晰的纸币图像数据.选用三段式多光源接触式图像传感器采集纸币的光感电压信号,经过模数转换电路,每行三段数据同时拼接成一行,每张纸币采集500行,组成一幅完整的纸币图像送到高速存储器进行缓存.经仿真分析与实验板验证,采用本系统进行纸币图像采集可以实现1 min采集约1 382张纸币图像,具有很好的实时采集效果.
Abstract:
The functions of banknote photoelectric conversion, analog to digital conversion and data cache were performed by field programmable gate array parallel technology. According to the collected images, banknote sorting system can realize authenticity recognition, banknote classification, worn coin distinguish and crown font extraction. The voltage signals of banknote’s light-sensing image were acquired with a three-section and multi-source contact image sensor. After analog to digital conversion, three-section data were spliced into one line, and 500 lines were spliced into a image saved in cache. Through the simulation and the experimental verification of banknote image acquisition board, about 1 382 pieces of banknote images are achieved in a minute. It proved that this method has a good effect of real-time acquisition.
