Abstract
Fingerprint identification system for power grid operation terminal has many defects,such as a little bit of high FRR and FAR,slow running speed when executing complex algorithm and high hardware cost.In order to overcome the insufficiency,this paper put forward the fingerprint identification system with high performance-price ratio based on ADSP-BF531.Hardware design and fingerprint identification algorithm was carefully described.Hybrid filter used for fingerprint enhancement combing Gabor and FFT× [FFT|n filter was especially studied.Experiment results show that this fingerprint identification system has high recognition accuracy and the real-time performance can meet the requirement.关键词
