Aiming at the problem of image acquisition palmprint recognition system , this paper puts forward a design method of palmprint image acquisition system based on CPLD and DSP . According to the special structure of DSP , it is vsed as the algorithm processing core to collect , store and process palmprint image . Using OV7620 as the palmprint sensors , and using CPLD to complete the transformation logic signal between DSP and OV7620 , it designs a real-time palmprint acquisition system with high perfor-mance . Practice has proved that the image acquisition system is stable and reliable , has certain application and reference value .
