Abstract： Aiming at the shortcomings of price，efficiency and accuracy of fingerprint algorithm in the embedded fingerprint identification system at present，an embedded fingerprint recognition design method based on STM32 and FPS200 fingerprint sensor was introduced. In the algorithm，Gabor filter enhancement and image recognition accuracy were improved by seeking the fingerprint orientation field information，and recognition efficiency was enhanced by initial match and global similarity method. The results indicate that the system identification has high accuracy，high efficiency，overall performance meet the requirements.
Key words： fingerprint recognition； STM32； fingerprint sensor； recognition algorithm
