摘　　要：静脉识别技术的快速发展对手指静脉识别系统的实用性提出了更高的要求。提出了一个基于嵌入式的具有调光功能的手指静脉图像采集系统,并详细讨论了采集系统的工作原理、嵌入式系统下USB摄像头驱动程序的编写、光源控制电路的实现以及采集应用软件的开发。实验结果表明,在实现手指静脉采集装置便携化的同时,系统可稳定获取不同粗细手指的清晰静脉血管图像。因此,本系统具有较好的实际应用与推广价值。The rapid development of finger-vein biometrics raises a higher requirement for the performance of real finger- vein recognition systems. An embedded finger-vein image acquisition device is proposed. The principle of the acquisition system is discussed in details, as well as the embedded driver of USB camera, the light control cir- cuit and the image acquisition software. Besides making the finger-vein acquisition device more portable, the experimental results also show that the proposed embedded system can successfully and clearly capture vein im- ages of fingers with different thicknesses. Hence, the proposed system is applicable and valuable in practice.
