摘 要
为了改善特定身份鉴别持有物和特定身份鉴别知识这两大类传统身份鉴别方式的不足.使身份鉴别变的简单安全便捷，设计了一个指纹模式识别系统。指纹模式识别系统是基于C++，以Visual C++6.0 作为开发工具设计完成的。系统的主要模块有指纹图像采集模块、指纹图像预处理模块、指纹图像特征提取模块、指纹图像匹配模块。指纹图像预处理模块主要完成指纹的真实化处理、智能化增强、二值化的工作，为提取指纹框架做好准备。主要设计的算法有指纹畸变校正、指纹分割、指纹均衡、智能化增强、二值化和细化处理。指纹图像特征提取模块提取的特征点主要是端点、交叉点、中心点和三角点这四大类点。指纹图像匹配模块主要是利用指纹特征点的拓扑数据结构来进行比对的。设计的系统经实验验证，科学有效。

Abstract
In order to improve the traditional authentication which the authentication of specific holdings and specific knowledge，to make the authentication changing safe and convenient, design a fingerprint pattern recognition system. Fingerprint pattern recognition system is based on C++ and applying Visual C++6.0 as development tool. The main modules of the system are image acquisition module, fingerprint image preprocessing module,fingerprint image feature extraction module and fingerprint image matching module. The fingerprint image preprocessing module is to complete three work which the true fingerprint preprocessing, intelligent enhancement and binary, and prepare to extract the fingerprint’s framework. The main designs are include fingerprint distortion correction algorithm, fingerprint segmentation, fingerprint balanced, intelligent enhancement and binary and thinning. Fingerprint image feature extraction module is mainly extracted four categories points which end, intersection, center and triangulation point. Fingerprint image matching module is using of fingerprint feature topological data structures for matching pairs. The test verified the above system, scientific and effective.
