基于TMS320VC5471嵌入式的生物识别系统的开发应用

介绍一种基于TMS320VC5471嵌入式的可用于门禁、考勤、管理、银行等需要身份识别的行业和场合的生物识别系统的组成结构、硬件设计及软件编程。根据生物识别系统所用到的两类特征：生理特征和行为特征,选择不同的传感器,使用不同的生物特征提取算法完成不同的生物特征识别,以其确认身份。系统界面简洁,操作方便,具有高准确率和高稳定性。

The developmental application of an embedded biometric identification system based on the TMS320VC5471

This paper presents an embeded biometric identification system based on the TMS320VC5471, which is used to meet the need of security arrangements, such as entrance guards, workattendance check,management work, bank system, etc. The paper also describes the hardware design and software programming of the system. According to the two kinds of biometriC characteristic, that is, physiology and behavior characteristics, different sensors shoud be choosen and different kinds of biometric identification technology algorithm need applying to the biometric character identification and identity authentication. The system interface is very simple to operate and boasts high accuracy and reliability.
