基于虚拟现实技术的协同式3D多人应急演练平台设计

Design of A Collaborative 3D Multi-person Emergency Drill Platform Based on Virtual Reality Technology

针对现有火灾救援应急演练场景渲染速率较低的问题,提出基于虚拟现实技术的协同式3D多人应急演练平台设计。地形模块用于在协同式3D多人应急演练平台中进行地理信息展示。演练导播模块的交互界面为仿真度极高的三维实景。该模型主要通过虚拟现实技术来构建协同应急演练的虚拟场景模型。数据库模块支持服务器模块中的数据操作包括数据入库、数据查询。并将其应用于应急演练中,对平台是否满足设计预期进行测试。实验结果表明,该平台的可视化映射速度平均可达12.54 ms;场景渲染速率平均达到了33帧/s,验证该平台的良好性能和良好的应用前景。

Aiming at the low rendering speed of the existing fire rescue emergency drill scene,a collaborative 3D multi person emergency drill platform based on virtual reality technology is proposed.Terrain module is used to display geographic information in collaborative 3D multi person emergency drill platform.The interactive interface of the drill guide module is a highly simulated three-dimensional real scene.This model mainly uses virtual reality technology to build the virtual scene model of collaborative emergency drill.The database module supports the data operation in the server module,including data storage and data query.And it is applied to the emergency drill to test whether the platform meets the design expectation.The experimental results show that the average mapping speed of the platform is 12.54 Ms;The average rendering rate of the scene reaches 33 frames/s,which proves the good performance and good application prospect of the platform.
