Abstract


The earliest , is the most widely used biometrics fingerprint recognition is used in the field of pattern recognition . Automated Fingerprint Identification System has wide application background, currently common PC -based fingerprint recognition software for WINDOWS operating system and a fingerprint scanner connected via USB interface and PC is already technically very mature , and has begun a large - scale promotion . However, based embedded systems , DSP system , fingerprint recognition technology , both in hardware design algorithm software are just getting started, the excellent performance of the algorithm on a PC is not necessarily simply transplanted to the DSP system . However, with the vigorous development of mobile communications and portable devices introduce new fingerprint recognition technology in the future will be more used in embedded devices , therefore , to study the Automated Fingerprint Identification System Based on DSP platform for the expansion of the DSP applications use fingerprint recognition to the offline development and improve the flexibility of the system , the real-time nature of great significance . This paper first introduces the development status of the fingerprint recognition system , as well as the difficulties and the development direction of the fingerprint recognition technology , fingerprint collection technology . Japan BMF BLP-100 pressure fingerprint sensor system core processor the TMS320VC5409 DSP of TI's chip fingerprint image acquisition devices , the shaping and logic circuit using BMF company BCT - 100 . Complete the fingerprint chip selection and the basic functions of semiconductor fingerprint sensor , based on the basic internal structure of the fingerprint sensor designed fingerprint capture sub- board fingerprint collection . Another research focus of this paper is focused on the structure - based fingerprint recognition algorithm principle and its various components : fingerprint center point calculation , fan , normalization method , Gabor filtering , feature extraction and matching , and finally use Matlab7.0 programming recognition algorithm of this system . Fingerprint identification system DSP technical feasibility of exploration , simulation results verify the feasibility of the system .
