摘要
系统以嵌入式微处理器S3C2440和Linux为核心平台,采用USB摄像头作为图像采集设备,利用Linux下视频设备应用编程接口V4L2和Qt/Embedded实现图像的采集,实时显示和JPEG格式图片保存,利用libjpeg库来实现视频数据的编解码以及通过以太网进行远程传输,实现一种功耗低、可靠性高和低成本的网络图像采集与传输系统设计方案。
The system uses embedded microprocessor S3C2440 and Linux as the core platform.The application programming interface V4L2 and Qt/Embedded library are two key technologies to realize image acquisition,real-time display and JPEG picture saving by using USB camera.This design of image acquisition and transmission is a low power consumption,high reliability and inexpensive system,which achieves encoding or decoding of images by libjpeg library and remote transmission of Ethernet.
