摘　　要：采用以基于ARM7内核的微处理器LPC2210为核心及CMOS图像传感器OV7620,设计实现了基于ARM微处理器的嵌入式指纹图像采集系统。重点说明了如何设计、制作和调试基于LPC2210及其外围电路的硬件平台和LPC2210与OV7620的硬件连接过程。然后在ADS1.2集成开发环境下开发了指纹采集程序,进行了实验调试并正确采集到了指纹图像。实验结果表明,所设计的系统具有较好的处理速度,较高的可靠性和稳定性,能够满足指纹识别系统对图像采集的基本要求,具有很强的实用价值。In this paper, using microprocessor LPC2210 based on ARM7 kernel as core and CMOS image sensor OV7620, design and implement fingerprint image acquisition system based on embedded ARM microprocessor. This paper focus on how to design, product and debug hardware platform based on LPC2210 and LPC2210 its peripheral circuits as well as hardware connection process of LPC2210 and OV7620. Afterward, under integrated environment of ADSl. 2, developed fingerprint acquisition procedures , Conducted experimental debugging and captured correct fingerprint image. The experimental results show that designed system has good processing speed, higher reliability and stability to meet the basic requirements of fingerprint identification system for image acquisition and has a strong practical value.
