基于DSP平台的人民币编号识别系统的设计与实现

摘要

为了在嵌入式系统中实现实时视频图像人民币号码识别，提出了基于TI系列TMS320DM642的快速人脸检测系统设计方案，包括系统软件和硬件的方案。首先，详细介绍了人民币编号图像提取与识别，针对该算法实现原理阐述硬件平台上的算法移植和优化方案，最后，实现了嵌入式快速人民币号码识别系统的研制。通过分析测试结果，系统可靠运行，优化后系统运行速度提高，能够实现实时人民币号码识别。%In order to realize the rea-l time serial number recognition system in video by embedded system,the design scheme of serial number recognition system based on TI TMS320DM642 was presented,including both hardware and software.Firstly,the algorithm of extract and recognize the image of RMB serial number was introduced in detail,then according to the algorithm,the algorithm was transplanted onto the hardware system,then the optimization policy was applied.Final y,the fast embedded RMB serial number recognition system was implemented.The experimental results demonstrate the system works reliably,the running speed of algorithm was improved markedly,and real-time RMB serial number recognition was realized.
