Abstract:

The research of embedded finger-vein recognition system is beneficial to the application and popularization of finger-vein recognition device. A finger-vein recognition system based on embedded Linux platform is designed and implemented, the construction of system hardware platform and the software development are discussed in details. The main contributions are as follows: a. the system structure is optimized; b. finger-vein image preprocessing, feature extraction and recognition algorithm are embedded in the system; c. system dynamic register function is realized; d. the traditional feature data storage mode is improved, and the new embedded database technology is adopted. Experimental results show that the system is stable and reliable, and has a higher recognition efficiency.

Key words: embedded system, finger-vein recognition algorithm, embedded database technology
