基于无人机的实时图传系统
|
摘要
民用领域上无人机的航拍系统,不仅给专业工作者带来方便,还给普通生活带来了乐趣。本文以无人机本身自带的图传系统为基础通过视频处理技术将视频流处理后通过Android手机4G网络实时上传到搭建好的服务器上,同时也将无人机飞行参数一并上传,然后通过PC端获取服务器的视频流数据以及飞行参数,PC端通过软件能实时显示前方无人机拍摄的画面以及当前无人机的飞行状态。
With the development of Unmanned Aerial Vehicle(UAV) technology,it shines brilliantly in various fields.Aerial photography system of UAV in civil field not only brings convenience to professional workers,but also brings fun to ordinary life.Based on the image transmission system of the UAV itself,this paper uses video processing technology to process the video stream and upload it to the established server in real time through the 4 G network of mobile phone. Meanwhile,the flight parameters of the UAV are also uploaded. After that,the video streaming data and flight parameters of the server are acquired through the PC terminal. The PC terminal can display the pictures taken by the UAV in the front and the current flight status of UAV in real time through the software.
