摘要
针对目前视频监控的实际需求,结合嵌入式技术、图像处理技术,设计并实现了一种可靠性高、成本低的嵌入式无线视频监控系统;系统选用S3C6410微处理器作为主控制器,利用USB摄像头进行采集,利用S3C6410的硬件编解码模块进行H.264编码,采用实时传输协议通过无线局域网(基于802.11g)进行视频传输;测试表明,系统设计合理,视频采集编码效率高、图像连续性好、传输丢帧率低,运行稳定。
Aiming at actual demand of present video monitoring, a reliable and cheap embedded video monitoring system is designed and realized, with the combination of embedded teehnology and image processing technology. This system chooses S3C6410 as the kernel board＇s controller, uses USB camera to capture pictures, encodes the video data using the codec of S3C6410 and transfer them through wireless LAN （based on 802. 11g） by using RTP protocol. The test shows that this system is designed reasonable, has a high efficiency to capture video data, has good continuity for pictures and low frame loss rate and can run stably.
