生物计量学掌纹识别非接触图像采集方式清晰度评价模拟系统 biometrics palmprint recognition non-contact image acquisition clarity evaluation simulation system

摘要

为了保证非接触式掌纹识别系统所采集的掌纹图像清晰度能够满足识别要求，缩短用户的测试时间，建立了图像清晰度与掌纹错误识别率的关系模型，并实现改进的非接触式在线掌纹识别模拟系统。引入图像清晰度评价函数，建立图像清晰度函数与物距（手与镜头的距离）之间的关系模型；进一步建立图像清晰度与该清晰度下掌纹识别系统错误识别率的关系模型；实现改进的基于清晰度评价模块的非接触式掌纹识别模拟系统。实验结果表明，改进的模拟系统保证了非接触式掌纹识别图像采集的成像质量，降低了错误识别率，具有实用价值。

Abstract

To guarantee the palmprint image definition satisfying user′s requirements acquired by non-contact palmprint recognition system and shorten recognition testing time, the relation model between palmprint image definition and error recognition rate is established, and the improved non-contact on-line palmprint recognition simulation system is realized. The image definition evaluation function is introduced, and the relation model between image definition and shooting distance is established. The relation model between image definition and error recognition rate is established. The non-contact on-line palmprint recognition simulation system is realized which is based on image definition evaluation module. The experimental results show that the improved simulation system ensures the effectiveness of the image acquisition and reduces the error recognition rate.
