摘要
以三星公司的OK6410开发板为硬件平台,以嵌入式Linux-3.0.1为软件平台,以Omni Vision公司的OV9650图像传感器为视频图像获取工具,通过V4L2编程接口实现摄像头获取视频图像数据,最终实现了嵌入式Linux平台下CMOS摄像头对视频图像的采集、在开发板上的显示及抓取图像并保存至SD卡,画面稳定流畅.重点介绍了OV9650的工作原理以及与开发板的接口原理,详细叙述了BootLoader移植、内核移植和根文件系统制作等步骤,为系统设计和其他嵌入式开发提供参考.
In this study,the small system has been designed with the hardware platform made up of Samsung′s OK6410 development board as well as the embedded Linux-3.0.1software platform,with Omni Vision′s the OV9650 sensor image for video image capture tool,through the V4L2 programming interface to acquire video and image data from the sensor,and finally realize to acquire the video and image from the CMOS camera based on the embedded Linux platform,display stable and smooth picture on the development board and capture images saved to the SD memory card.The paper mainly introduces the working principle of OV9650 and the interface principle on the development board,also details the BootLoader transplant,kernel transplant and making root file system and so on,that provide a reference for designing this paper and further embedded development.
