摘要
设计一种基于ARM的移动视频监控系统,介绍嵌入式系统下视频压缩、编解码库的移植与应用,视频流媒体的传输与控制。系统由视频采集端和移动监控端组成,视频采集端主要功能包括视频数据采集、压缩编码、传输及控制;移动监控端采用Android智能手机借助3G无线网络连接视频采集端,从而实现远程无线视频监控功能。实验结果表明,视频图像清晰、播放流畅、延时小且系统稳定可靠,达到了系统的设计要求。
A mobile video monitoring system based on ARM was designed. The video compression,coding,decoding library transplantation,and the transmission and control of stream media under the embedded system are introduced. The system consists of video data acquisition terminal and mobile monitoring terminal. The video data acquisition terminal includes video data acquisition,image compression coding,video transmission and control. The mobile monitoring terminal is connected with video acquisition terminal by means of Android smart phone via 3G wireless network to achieve the remote wireless video monitoring. Experimental results show the system is stable and reliable,its video image is clear;video play is fluent,time delay is short,which can meet the requirements of the system.
