Fingerprint Identification System Based on DSP
Abstract: In this paper, the dual processor fingerprint recognition system based on DSP and MCU, at the same time to do some research on fingerprint recognition algorithm. The core part of the whole system is TI company's TMS320VC540, AT89C52 and FPS200 fingerprint. According to the acquisition circuit diagram of the fingerprint design the man-machine interactive system and power supply circuit design, And the design ideas and working principles are described In the research of fingerprint algorithm is mainly divided into three steps, Fingerprint image preprocessing, Feature points extraction of fingerprint image. At the end of the paper, the debugging of the whole recognition system, simulation results obtained.
Key Words: FPS200; TMS320VC5404; AT89C52
