基于Android平台的非接触指纹识别研究

Implementation of non-contact fingerprint identification based on Android platform

提出一种利用手机摄像头获取指纹在Android平台中进行实时指纹识别的方法。采用多尺度Harris角点检测和ORB图像匹配算法进行特征提取与匹配,并运用Android开发工具和Open CV对其技术实现,最后分别在不同的Android移动设备上进行实验和测试。实验结果表明此方法能够在Android平台上进行实时的指纹图像的采集、注册与识别,具有较高的识别率和稳定性,基本满足移动平台非接触式指纹识别的需求。

A method of real-time fingerprint identification using the camera on mobile-phone to acquire fingerprints in Android platform is proposed. Multi-scale Harris comer detection and ORB image matching algorithm are used for feature extraction and matching, furthermore Android development tools and OpenCV are used for technical implementation, respectively experiment and test in Android different mobile devices. The experimental results show that this algorithm can acquire, register and recognize the fingerprint images in real time on the Android platform, and it has higher recognition rate and stability to meet the requirements of contactless fingerprint identification on mobile platform.
