摘要
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 realize the processing and recognition function. Experimental results show that the system is definitely suitable for embedded vein recognition.
