摘　　要：本文实现了由ARM9芯片AT91RM9200和滑动指纹传感芯片AT77C104BFingerChip构成的、基于Linux的指纹采集系统。同时利用一种快速的指纹拼接算法,拼接出完整的高质量指纹图像,使低成本、低功耗和小面积的滑动指纹传感器达到与传统的指纹传感器相同的效果。This paper elaborates on the implementation of a fingerprint acquisition system based on the embedded Linux environment, which？consists of ？the ARM9 AT91RM9200 and the sweep fingerprint sensor AT77C104B FingerChip. The whole high quality fingerprint is obtained by a fast stitching algorithm. The effect of fingerprint obtained by the low cost, low power and small area sweep fingerprint sensor is as good as traditional one＇s.
