摘　　要：针对单一的透射式和反射式近红外手掌静脉成像技术在不同手掌区域效果不一而使静脉成像效果低的情况,设计了一种采取透射式和反射式成像相结合来获取手掌静脉血管图像的系统。根据近红外成像原理,分别获取反射和透射两种手掌静脉图像,接着,对得到的静脉图像分别进行信号增强处理,最后进行融合。实验结果表明,该系统能够得到完整和清晰的手掌血管图像,且在临床静脉穿刺,生物身份特征识别上有很大价值。Aiming at the situation that venous imaging effect is low because the single transmissive and reflective near-infrared palm vein imaging technology has different effects in different palm areas,a system that combines transmission and reflection imaging is designed to acquire palm vein images.According to the principle of near-infrared imaging,the reflected and transmitted images of palm veins are obtained.Next,the obtained vein images are separately processed for signal enhancement and finally fusion.The experimental results show that the system can not only get a complete and clear images of palm blood vessels,but also have great value in clinical venipuncture and biological identity recognition.
