摘　　要：为避免灾难发生时因经验不足导致慌乱而造成更大的损失,使用混合显示技术设计一种应急仿真应用系统。硬件设计中使用蓝牙适配器作为无线网络传输的工具;软件设计中基于混合现实技术重建虚拟现实场景,对图像进行降噪处理,计算各像素点的3维坐标,实时更新粒子位置,对其进行可视化渲染,并获取粒子在混合现实场景渲染下的位置坐标,混合现实视线下的投影距离;对应急逃生路径规划设计一种路径规划算法;在仿真场景的物理模型下,获取应急疏散模拟结果。结果表明:该仿真系统具备实用性,能够完成应急演练时的数据收集与分析。In order to avoid the panic caused by the lack of experience when the disaster occurs,a hybrid display technology is used to design an emergency simulation application system.Bluetooth adapter is used as a tool for wireless network transmission in hardware design;In the software design,the virtual reality scene is reconstructed based on the mixed reality technology,the image is denoised,the three-dimensional coordinates of each pixel point are calculated,the position of the particle is updated in real time,the visual rendering is carried out,and the position coordinates of the particle under the rendering of the mixed reality scene and the projection distance under the line of sight of the mixed reality are obtained;Obtaining an emergency evacuation simulation result under the physical model of the simulation scene.The results show that the simulation system is practical and can complete the data collection and analysis during the emergency drill.
