摘　　要：基于指纹图像处理准确性高、实时性强等实际要求,介绍了一种指纹图像处理方法。Linux系统下用基于fps200芯片的指纹采集系统采集指纹图像,并用QT编程实现了指纹图像采集、处理的整个过程。通过研究,提出了满足要求的方向增强以及细化算法。整个处理过程实时性强,处理后指纹图像细节特征保存较好,可以胜任AFIS的前期工作。The processing of fingerprint image has the requirements of high-veracity and strict real-time request. An algorithm is introduced for fingerprint image processing. The image is captured by fingerprint capture system based on chip fps200 and realized with QT in Linux. Through the research, an algorithm is put forward which can satisfy orientation enhancement and refining requirement. The total image processing has highly realtime performance, and the processed images can reserve the minutia features very well. It can be integrated into practical AFIS.
