多光谱手指静脉成像与采集系统设计

多光谱手指静脉图像信息采集对提高手指静脉识别性能具有重要意义,从活体组织的不同介质对不同波长的入射光有不同的散射和吸收性能这一角度出发,建立了多光谱手指静脉成像采集系统。重点介绍基于数码管控制芯片的多波段光源控制电路而搭建的硬件系统及设计的相应软件系统。该系统不仅解决了多模态手指静脉图像成像与采集的一些基本问题,而且为多光谱手指静脉识别奠定了数据基础和实验环境。这对促进手指静脉识别技术的发展具有重要意义。

Design of multispectral finger vein imaging and capturing system

Multispectral finger-vein image acquisition is of great important for finger-vein recognition.In this paper,a multispectral finger-vein image acquisition system is therefore established considering that the optical properties of the biological tissues vary with wavelength of incident light.Firstly,the hardware including multispectral light control circuit based on the chip is designed.Secondly,the image capturing software is designed.This established system can be capable of solving some basic problems in multimodal imaging and acquisition.Finally,an experimental environment for multispectral finger-vein recognition is constructed.This is of great important for the development of finger-vein recognition technology.
