MR技术在小流域山洪灾害防治中的应用研究

Application of Mountain Flood Disaster Prevention and Control in Small Watershed Based on MR Technology

摘要: 随着科学技术的发展，VR、AR、MR等技术日益完善，作为虚拟现实成像领域最前沿的技术，该技术将会广泛应用于小流域山洪灾害场景模拟中。本文通过MR系统把山洪灾害防治的现实环境构成虚拟场景，利用专业引擎去与GPU互换数据，动态渲染模拟光源，实现在MR中模拟演示山洪灾害暴发过程，并结合当地山洪灾害防御体系建设情况，模拟演示灾害发生过程中当地监测、预警、转移安置、抢险救灾等应急响应工作。该技术将充分发挥信息化技术对基层防汛业务管理水平的提升，提高自身防灾减灾意识和灾害避险能力，从而减少因山洪灾害造成的人员伤亡和财产损失。

Abstract: With the development of science and technology, VR, AR, MR and other technologies are becoming more and more perfect. As the most advanced technology in virtual reality imaging field, this technology will be widely used in the scene simulation of mountain flood disaster in small watershed. In this paper, the real environment of flood disaster prevention and control is composed of virtual scene by MR system, using professional engine to exchange data with GPU, dynamically rendering analog light source, simulating and demonstrating mountain flood disaster outbreak in MR, and combining with the construction of local flood disaster defense system to simulate demonstration of local monitoring, emergency response, relocation, emergency rescue and disaster relief during the process of disaster occurrence. The technology will make full use of information technology to improve the level of flood control management at the grass-roots level, improve the consciousness of disaster prevention and disaster reduction, and reduce the casualty and property loss caused by mountain torrents.
