基于QoE的遥在机器人系统网络视频传输优化算法

iming at the problem of video quality on the operation side in telepresence robot system, an optimization algorithm of video transmission in telepresence robot system based on QoE(Quality of Experience) was presented in this paper. Firstly, considering to the mobility of the telepresence robot and the velocity of target in the scope of camera, the identification of the system is conducted for computing the QoE of network's and user's. Then the optimization function is established. In order to improve the video quality on the operation side, the parameters of video transmission which affect QoE are optimized in multivariable optimization method. The user tests showed that this algorithm can reduce the packet loss, improve the video quality and operation experience in limited bandwidth.
