摘要
本嵌入式无线视频监控系统采用高性能ARM9芯片作微处理器,通过嵌入式Linux采集USB摄像头视频数据,并将采集的视频数据帧经JPEG压缩;在ARM9芯片的控制下,通过2.4GHz无线发送/接收模块进行视频数据传输;无线接收端再将视频数据通过网络接口提交给视频应用服务端;最后由视频应用服务端将接收到的压缩数据帧重组、复合成视频图像,实现无线视频监控。
The embedded wireless video capture system design takes high performance ARM9 chip as MPU, it captures USB camera video via embedded Linux, and compresses the digital video data through JPEG compression ;ARM9 chip controls 2.4GHz wireless sender/receiver to transfer digital video data from video capture end to video transference end; After receiving video data, transference system sends it to video application service end by RS232 or RJ45 interface; at last, video application service end recombines the video data,produces digital video and achieves wireless video monitoring.
