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。
关键词: Linux, 图像采集, Qt/Embedded, V4L2, S3C2440
Abstract: 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, realtime 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.
