摘要
文章以S3C2440开发板为硬件平台,构建了一个基于ARM9处理器的虹膜图像采集系统,并分析了如何在该平台上实现虹膜采集。同时阐述了系统的硬件架构和接口设计,提出了基于V4L标准的摄像头接口设备驱动程序框架,并详细介绍了视频采集程序的具体实现过程,进而提出了一种可行的嵌入式实时图像采集驱动设计方案。实际使用结果表明,本设计方案能充分满足便携式虹膜采集设备的需求。
This paper has build a iris imaging system and describe how to achieve iris image-capture on the platform,the platform chosen is S3C2440 developing board.Also expounds the hardware architecture and interface design of system.Furthermore,we propose the implementation framework of the camera interface based on V4L protocol standard,and introduce detailedly the program of video collection.In addition,we has presented a driver design scheme of embedded real-time image captioning.So it meets an excellent portable video capture device.Fimlly,the practical experiences show that this design scheme can fully satisfy the requirement of portable image capture device.
