Abstract:
With the development of biology identification technology, fingerprint identification becomes more and more mature and gradually develop from the online machine system to embedded system. At present the fingerprint capturing module generally uses optical sensor in embedded fingerprint system. The volume of this kind of sensor is big and it is diseommodious for integration in embedded system. The article puts forward a kind of new method and uses semi - conductor fingerprint sensor FPS200 to capture fingerprint images. It studies the hardware connection of FPS200 and the processor chip TMS320VC5416 ,the initialization of FPS200 and the programme of fingerprint capturing. The article gives finally the fingerprint image that FPS200 captures. The experiment proves that the image veins is clear, the background noise is small and the speed of capturing fingerprint image is quick. These can satisfy the requirement of the embedded fingerprint identification system .
