摘要
为了满足视频监控、视频对讲等视频采集实时性的要求,设计应用嵌入式技术,以S3C2440为系统硬件核心,负责分析和处理使用USB摄像头采集的视频数据内容,在Linux操作系统下使用MPEG-4编码对视频进行压缩并通过网络传输,通过V4L2驱动为摄像头提供接口函数,实现了远程实时的视频采集和传输的工作。该系统具有体积小、成本低和功耗低等特点,经测试结果表明,系统的视频采集清晰,视频传输流畅可靠,具有良好的使用性和扩展性。
To meet the requirement of real-time video acquisition, such as video monitoring and video intercom, the design uses embedded technology and S3C2440 as the hardware core responsible for analyzing and processing the USB camera of video data collection, uses MPEG-4 encoding under the Linux operating system to compression and transmission video data, via V4L2 driver provides an interface function for the camera, to achieve real-time remote video acquisition and transmission. The system has small volume, low cost and low power consumption, the tests reveals that the system of video acquisition is clear, smooth and reliable video transmission and has good usability and expansibility.
