This paper proposes a new palmprint sampling system based on the DSP corresponding to the current system structure that it adopts scanner or image sampling card to sample palmprints and realizes the recognition process with PC. This paper a new palm-print sampling system based on DSP. The system changes the palmprint images into digital images through the SAA7113H vision decoder and realizes the sampling and recognition in the off-PC state by taking advantage of the TI DSP TMS320VC5509A control chip. The best optical source and optical structure to sample the best plamprint images is acquired by the experiments whose result show that this system satisfies the real-time requests and has a very high recognition rate.
