摘　　要：采用新型刮擦式指纹传感器AES2510设计的指纹采集系统。简单介绍了AES2510的结构特点及其与处理器TMS320VC5416的硬件连接方法,重点研究了采集系统的软件设计,并根据采集图像的特点提出了一种简单实用的指纹图像重组算法,最后给出了实验结果分析。This paper introduces a fingerprint acquisition system which is designed by a new swiping fingerprint sensor AES2510. The structure features of AES2510 and the hardware connection with TMS320VC5416 are presented. The software design of the acquisition system is thoroughly studied and an algorithm for reconstructing fingerprint imagers based on the characteristic of the images is offered, and finally the analysis of the laboratory results comes out.
