摘要:
本系统采用博创公司UP-Magic S3c2410开发平台,充分利用该平台强大的嵌入式微控制能力。本系统采用的指纹图像算法主要分为三个部分:预处理、特征提取和匹配。其中预处理部分由归一化、分割、二值化、去噪、细化等算法组成,且在特征匹配算法中使用了对图像旋转和平移无关的数学模型。本课题设计的系统工作方式采用了登记方式,在登记方式下,指纹传感器采集指纹图像数据并保存至内存,在UP-Magic S3c2410上移植的指纹识别算法完成对指纹图像的数字化处理,将形成的特征样本保存。通过对此平台的实验测试,表明该系统采用的指纹识别算法具有较好的实用性、移植性和识别效率。系统通过参数调整可以达到一定的拒真率和误假率,能够满足民用指纹识别领域的基本要求。

Abstract:
Our system adopt the development platform called UP-Magic2410 of UP-TECH Corporation,which fully uses the strong embeded microcontrol ability of the platform. The algorithm of the system is posed of three parts: pretreatment、feature extraction and the three parts, pretreatment is maded up of the Algori--thm such as normalization ,division ,binarization, denoising ,thinning and math model which is beyond out of pictureorientation and translation is used in the process of feature working way of the designed system of the subject employed the way of the way of it , Fingerprint Sensor collect the data of Fingerprint Image and stored it in fingerprint identification Algorithm which is transplanted in the platform of UP-Magic S3C2410 plished the digitization dispose and stored the featured sample formed in the testing the platform,it indicates the fingerprint identification algorithm of the systerm have preferable pra--cticability,portability and identified efficency. The systerm can achive the goal of certain FRR by ajusting the parameters ,thus satisfying the fundamental requirem-ent of the fingerprint idetification field.
