| 摘 要： | 基于Linux2.6内核下的最新标准Video For Linux 2(简称V4L2),介绍摄像头的驱动程序快速开发方法.传统的驱动开发很少能实现所有的接口功能,这严重影响到系统开发周期与维护工作,而且OmniVision公司的ov9650摄像头在Linux下尚未得到驱动支持.本文选择S3C2440开发板作为硬件平台,在Linux2.6.30.4系统下基于OV9650传感器芯片实现摄像头驱动模块的层次结构以及视频采集模块设计的开发工作,提出基于V4L2接口规范的驱动开发方案,从而实现低成本、低功耗、高效率的图像检测系统的应用.

| Abstract: | Based on the latest standard Video for Linux 2(V4L2) in Linux kernel 2.6,this paper introduces the rapid development method of driver programs.Traditional driver development is rarely able to realize all the interface functions,which seriously affects the system development cycle.The ov9650 camera driver of OmniVision Company has not been supported by Linux kernel.For this reason,under the condition of s3c2440 board hardware platform and Linux kernel 2.6.30.4,the authors of this paper achieve development work including camera driver module hierarchy and video capture module design,put forward the method of driver development based on V4L2 interface specification,and realize the application of low-cost,low-power,highly efficient image detection system. |
