Abstract
In this paper, we introduce the basic structure of fingerprint identification system and its main program. We also discuss on how to design a fingerprint identification system in two aspects including hardware system and software system. Hardware system is based on the circuit connection with the series of MCS-51 chip, FPS200 fingerprint sensor and RS232 interface chip, and also including the program design of the chip; software system is included two main aspects, image processing and image identification, and we give the program of the image processing puter language(MATLAB). The results show that the images acquired from the system proposed in this paper are more clear and less distorted, and the processing images are more distinguish , the images after transform are wonderful prepare for classification and identification of fingerprints.
The full text contents include five chapters: 1. The first Chapter is introduction; 2. The second Chapter is the design of the hardware and the receive program of data. 3. The third Chapter is the Implement Algorithm of image processing and the image identification ; 4. The fourth Chapter is the implement of main Algorithm and analysis of experiment; 5. The fifth Chapter is summary.
Key words: fingerprint identification; FPS200 fingerprint sensor; the series of MCS-51 chip; image processing; image identification
