摘要

针对目前使用的传统电容式指纹传感器采集湿手指指纹效果差以及不能区别出"死手指"的现状

介绍了一款新型指纹传感器FPC1011F.重点介绍了该型号传感器的工作原理、性能优势及开发接口

在此基础上设计了基于ARM9核心S3C2440A微处理器的指纹采集系统.该系统采用S3C2440A微处理器的SPI口与FPC1011F进行连接

借助FPC1011F的时序图及官方资料进行了软件设计

利用MATLAB对采集的指纹数据进行了还原显示实验.实验结果表明:该系统采集的指纹图像稳定、纹理清楚、背景噪声小

并对干湿手指均有很好的适应性

对非人体指纹有良好的辨识性

为广泛使用该指纹传感器奠定了基础.

Abstract

For the traditional capacitive fingerprint sensor's poor fact in collecting the wet fingers and distinguishing the \!dead fingers\"

a new type of fingerprint sensor FPC1011F was introduced

focusing on the work principle of the sensor model

the performance advantage and the development interface.A fingerprint acquisition system was designed based on ARM9 microprocessor core S3C2440A by connecting SPI port to FPC1011F.The corresponding software was designed.The image data was processed with MATLAB.The experimental results illustrated that the system featured stabilization

clear texture of the image

low background noise

and good adaptability to both dry and wet fingers.The system is qualified in identifying the non-human fingerprints.The work lays the foundation for the extensive use of the fingerprint sensor FPC1011F.
