摘要

鉴于目前掌纹采集系统都采用扫描仪或图像采集卡采集掌纹，利用PC机来实现掌纹识别的系统结构，本文提出了一种新型的基于DSP的掌纹采集系统。通过视频解码器SAA7113H将掌纹图像转换成数字图像，利用TI公司的TMS320VC5509A DSP为控制芯片，实现了脱机模式的掌纹图像的采集。通过掌纹图像采集实验，得到了采集最佳掌纹图像的光源及光学结构。由实验所得结论，该系统满足实时性要求，有很高的识别率。

Abstract

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.
