摘要
指纹识别是一种主要应用于安防领域的一种成熟的生物技术,它利用了人体的指纹非常稳定、具有终身不变、不可丢失及唯一性的特点,解决了传统的安防系统存在损坏、丢失或替代等问题。目前在安防系统中利用指纹识别技术来进行身份认证是一种较好的解决方案,在社会得到了很好的推广应用。
本文讲述的指纹识别系统主要由以51系列的STC89C52单片机为控制器,以具有由高性能DSP 图像处理器和 FLASH 存储器等芯片构成的光学指纹传感器FM-180以及外部显示模块1602液晶三部分组成。由于光学指纹传感器FM-180本身具有指纹图像处理、指纹特征模板提取、指纹模板匹配、指纹搜索和模板存储等项功,所以它具有设备结构简单、易于维护、成本低、便于推向市场等优点。本文主要从软件设计方面入手,讲述软件总体设计方案、流程及各模块程序实现方案。

ABSTRACT
Fingerprint identification is a main application in the field of security in a mature biological technology, it used the fingerprint of the human body is very stable, with lifelong unchanged, must not be lost and the characteristics of the uniqueness, solve the traditional security system is lost or damaged, replace, etc. At present in the security system using fingerprint identification technology to carry out the identity authentication is a good solution, in social got very good promotion application.
This article tells the fingerprint identification system mainly consists of the single chip puter to 51 series STC89C52 for controller and with high performance DSP image by the processor and FLASH memory chips such as a optical fingerprint sensor FM-180 and external display module 1602 LCD of three parts. Due to the optical fingerprint sensor FM-180 itself has the fingerprint image processing, the fingerprint characteristics template extraction, fingerprint template matching, fingerprint search and template storage and so on a work, so it has simple structure, easy maintenance equipment, low cost, easy to market, etc. This article mainly from the aspects of the software design, overall design scheme about software, process and the modules program realization scheme.
