摘要
为了实现定位视音频数据的实时采集传输,本文设计了一种基于DM642的定位视音频采集器,该采集器采集、编码、同步、存储视音频和地理定位数据,并实时传输到远端服务器,远端服务器播放视音频信息同时刷新地图以定位。本文给出了采集器的硬软件设计方案,给出的测试结果证明了设计的可行性。本文的研究将促进地理信息系统的应用。
For sampling and transferring position video and audio data in real time,a novel video and audio position surveillance instrument based on DM642 DSP is proposed.The instrument samples,encodes,synchronizes,saves video audio and position data,and transports them to remote service for monitor in real time;the service plays video and audio data and refreshes map to position.The hardware module design and software flow chart are presented,and feasibility is proved by the test result.The research of this paper will promote the usage of GIS.
