The Research Of Remote Experiment Terminal Real-time Scene Reconstruction Technology

There is a problem of video transmission delay in the existing remote experiment system,which leads to the synchronization between experiment operation and phenomenon observation.In order to solve the problem of remote experiment asynchrony,the paper designs a remote experiment platform terminal scene reproduction system through the remote experiment terminal scene real-time reproduction technology?The main contents of the dissertation are as follows:1)Research on remote real-time transmission method of control instruction and experimental characteristic informationThe overall framework of remote real-time transmission platform for video characteristic information and control instructions is designed.The framework uses mqtt as the remote data transmission protocol.In the platform,the real-time remote transmission of control instructions and video characteristic information is realized by designing software and hardware,writing remote experiment terminal scene interface and building EMQ server.2)Research on feature information extraction method of terminal scene experiment videoThrough image processing and machine vision technology,study the method of extracting experimental video information and extract the feature data in the video image,which greatly reduces the amount of remote experimental video feature information transmission.3)Research fusion method of terminal scene and experimental feature informationThrough VR technology,the paper studies the fusion method of terminal scene and experimental feature information,designs the scheme of terminal scene experimental video feature information extraction and terminal scene and experimental feature data fusion.Realizes the interactive fusion of virtual experimental scene,experimental equipment and experimental feature information data,and solves the problem of experimental realism in remote experiment.Through the test of the terminal scene test platform,the video feature information in the experimental video is effectively extracted in real time,and the transmission time of the experimental operation and the experimental transmission is within 50 ms.finally,Control the experimental equipment in the remote real-time by the real-time reproduction of the experimental phenomenon.Solves the problem of different steps and realism in the remote experiment.
