摘要
手背静脉识别是新颖的身份认证技术,与指纹识别相比,具有活体识别、内部特征、非接触式等优点。基于近红外技术的手背图像采集设备具有制作成本低的优势,是实际应用中首选的技术。文章研究了基于近红外技术的手背静脉图像采集系统及制作,实验结果表明,在850nm的近红外光波下,可以采集到高对比度的手背静脉图像。对手背静脉身份识别系统制作具有参考价值。
Doisal hand vein pattern recognition is a new biometric identification technology, with the virtue of living body recogrfition, inner characteristic, and non-contact. The image acquisition system based on near infrared technology is popular because of lost cost. The system is designed using near infrared technology. The experimental results show that the system can capture high-contrast dorsal hand vein images under 850 nm near infrared.
