基于Linux的嵌入式网络摄像机设计

本嵌入式网络摄像机采用高性能ARM9 芯片微处理器，内置嵌入式Web 服务器。通过
嵌入式多任务操作系统采集摄像机视频数据；采集的视频信号数字化后经MJPEG 算法压缩，再通过内部总线送到内置的Web 服务器；使用者可以直接用浏览器观看Web 服务器上的摄像机图像；通过通用网关接口CGI，授权用户还可以控制摄像机、云台和镜头的动作或直接通过Web 页面对系统进行配置。

Abstract: This embedded web camera takes the powerful ARM9 chip as MPU，there is
a embedded web server inside it. The camera captures the video through embedded
multitask operating system；the digital video has been compressed by MJPEG algorithm
before it is sent to inner web server through interior bus；the users can view
camera’s video directly by internet explorer and the users who are authorized can
also control camera、the motion of cloud-station and lens or configure the parameters
of the embedded web camera straightly by Common Gateway Interface.
