学士学位论文 基于单片机的指纹识别系统设计The Design of fingerprint identification System Based on Single Chip 摘 要随着信息时代的进展, 自动指纹识别技术已经广泛地应用于公安、海关、银行、网络安全等需要进行身份识别领域。本文概述了自动指纹识别系统的讨论现状和进展状况，介绍了指纹识别系统的算法流程，以及在此基础上的指纹图像的分割算法和指纹图像细化算法。并完成基于单片机的指纹识别系统硬件电路设计。本文应用 ZMF-206 指纹识别模块，设计基于单片机的指纹识别硬件电路系统，形成一个独立的指纹识别控制系统。该系统能够实现单片机和指纹模块之间的串口通信，通过操作独立式键盘按键，向指纹模块的 DSP 芯片发送相应指令，从而执行录入用户、添加用户、认证用户、删除指定用户、删除全部用户、用户匹配等功能，适用于需要进行身份识别的领域。关键词：控制系统；指纹识别；单片机；串口通信Abstract With the development of the information age, automatic fingerprint identification technology has been widely used in public security, customs, bank, network security, and other areas of the identification is required. This paper summarizes the research status and development status of automatic fingerprint identification system, the algorithm flow of the fingerprint identification system are introduced, and on the basis of the fingerprint image segmentation algorithm, and fingerprint image thinning algorithm. And finish the fingerprint identification system based on single chip microcomputer hardware circuit design. ZMF-206 fingerprint identification module is applied in this article, the design for fingerprint recognition based on single chip microcomputer hardware circuit system, fingerprint identification control system to form an independent. The system can realize serial communication between SCM and fingerprint module, by manipulating the independent type keyboard key, to the fingerprint module of DSP chip to send corresponding instructions, to perfo...
