Image acquisition and storage are the premise of image processing and analyzing. The design scheme of embedded image acquisition and storage system on SOPC technology are researched. The design of image acquisition module and initialization are introduced in detail. By configuring Nios II CPU and some corresponding interface modules on FPGA and software design, image data can be stored in SD card. Experiment results indicate that the system works properly and has good application prospects.%图像采集与存储是对图像信息进行处理和分析的前提.针对目前嵌入式图像采集系统设计复杂、难以扩展升级、存储资源有限的问题,提出了一种基于SOPC技术的嵌入式图像采集与存储系统方案,用FPGA硬件逻辑资源实现了图像采集,在SOPC Builder中采用SPI内核完成了SD卡读写的硬件设计,在NiosⅡIDE环境下,采用C语言实现了图像SD卡存储的软件设计.实验结果表明,系统能够正常工作并具有较好的应用前景.
