低带宽环境下的三维协同标绘系统研究

3D Collaborative Plotting System in Low Bandwidth Environment

针对实际作战指挥中网络环境难以保障三维协同标绘的问题,文中研究了在低带宽环境下标绘数据的传输、解译和渲染展示方法,以及系统协同管理模式等关键技术,并设计开发了适应低带宽环境的三维协同标绘系统,实现在异地多用户之间实时同步三维场景和符号标绘,满足异地多用户专家和指挥作业人员协同标绘、指挥和决策需求。经过测试验证表明,该方法和设计的系统能够在低带宽环境下顺畅地完成基于三维场景的实时协同标绘,大大减少了系统对网络环境的依赖。

In order to solve the problem that it is difficult to guarantee the network environment of the site in the Operational coordination command. This paper studied the key technologies which are suitable for the low bandwidth environment, include the methods of the data transmission, interpretation, rendering, and the mode of system collaborative management. We also designed and developed a three-dimensional collaborative drawing system, which can realize the real time synchronization between multi users in different places, satisfy the demand of collaborative plotting, command and decision making. The test results shows that the method and system can smoothly complete multi-user collaborative plotting based on 3 D scene in low bandwidth environment, greatly reducing the dependence of the system on the network environment.
