| 摘 要： | 提出了一种基于ADSP-BF533的静脉识别系统设计方法。整个系统由静脉图像采集、静脉图像处理和识别两个模块组成。静脉图像由普通黑白模拟摄像机在近红外光照下获取;静脉图像处理和识别的核心单元是一颗ADI生产的Blackfin 533 DSP(ADSP-BF533),其速度可以满足后端处理的需要,可以实现静脉图像细化、特征提取及识别等功能。

| Abstract: | A design method of vein recognition system based on ADSP-BF533 is proposed.The system is composed by two function module groups: the vein image acquisition modules and the vein image processing and recognition modules.The vein images are acquired through a black-and-white analog camera under the illumination of near-infrared LEDs.The central unit for vein image processing and recognition is a Blackfin 533 DSP made by ADI(ADSP-BF533),whose work frequency is fast enough to relize the processing and recognitio... |
