Application And Study Of Biology Identification Technology Used In Security Of Equipment Storeroom

As a method of mature biology identification technology, fingerprint recognition technology has been made a great progress on the model of fingerprint structure, the technology of fingerprint gathering and the development of the commercial fingerprint recognition system, and there is a broad application prospect of fingerprint recognition system in different security control fields.In order to reform the traditional management pattern, we apply the biology identification technology in the fields of equipment storage management .At first, the paper introduced the feature and fundamental knowledge of fingerprint, the next,we discussed the pre-processing method of the fingerprint image and the feature extracting and matching.during the course of the pre-processing of the fingerprint image, we introduced the concept of direct image and filtrated the original fingerprint imag. At last, we enhanced the fingerprint image according to what we have needed. By doing these, we look forward to obtaining the best results of the fingerprint image feature extracting; At the same time, we set up the basic system frame based on ADSP2181EZ-KIT Lite according to the projects of the strucure of fingerprint recognition system, and designed the hardware and it' s interface circuits, some parts software of fingerprint recognition system have been designed according to the frame. Through processing the fingerprint image, we analyzed the results of the pre-processing image and the best method what we have chosen. At last, we have done some experiments about fingerprint matching, and analyzed its results.
