摘　　要：针对移动嵌入式应用,设计并实现了一种基于STM32的条状指纹实时采集与拼接系统。选用STM32F103RD作为主控器件,通过SPI接口以DMA方式获取AES1711传感器采集到的条状指纹,并采用快速算法拼接成完整的指纹图像。实验结果表明,本系统具有速度快、鲁棒性好、功耗低、性价比高的特点,可方便地应用在移动嵌入式设备中。For mobile embedded system applications, a swipe fingerprint capture and mosaicking system based on STM32 is designed and realized. STM32F103RD is used as main controller, the swipe fingerprint is captured from AES1711 by DMA through SPI interface, and then the fast algorithm is used to realize fingerprint mosaicking. Experimental results show that the system has fast speed, good ro- bustness, low power consumption and high cost--effectiveness, so it can be used in mobile embedded devices.
