基于ARM和Linux的视频采集系统研究与开发

Study and develop on the video capture system based on ARM and Linux

提出一种基于S3C2440、OV9650硬件平台和嵌入式Linux操作系统的视频采集系统方案。研究了视频采集模块电路设计和OV9650在Linux中的驱动开发,对系统总体结构、基于V4L的视频采集,以及视频压缩传输等功能模块设计做了具体介绍;试验结果表明,视频采集稳定,图像帧过度平稳,画质色彩较好,提供了一种成本低、体积小、功耗低的农业图像远程采集设备。

This paper introduces a video capture system scheme that based on S3C2440、OV9650 and Embedded Linux OS. We innovatively study and elaborate the design of video capture circuit and the driver of OV9650 in the Linux,and necessarily introduce the key modules：overall structure of the system、video capture based on the V4L、configuration of boa web server、video encoding and transmission.
