摘要
研究建筑物在不同出口条件设置下人员的安全疏散问题。针对人群仿真中如何计算疏散路径问题,文中采用导航图技术和agent技术来对个体进行疏散路径的规划。同时为表现人群运动过程当中个体之间的相互碰撞问题,结合碰撞规避规则进行穿透矫正。并且采用三维引擎Delta3D在VC++9.0环境下进行仿真并搭建了一套三维人群运动模拟平台。最后分别在三种不同出口条件下的虚拟场景中进行仿真。对比仿真结果表明该平台能直观地展现整个人群疏散的运动过程,并能够对建筑物出口安全设计的合理性提供有效的数据依据。
Study the subject of evacuation in buildings under different exits installed. Against the evacuation path problem＇of crowd simu lation, adopt navigation graph and agent method to solve the planning of individual path finding problem. Simultaneously in order to ex hibit the collision problem in the evacuation process ,built several rules to correct the penetration. At the same time use Delta3D built a complete three-dimensional crowd simulation platform under VC＋＋9.0 IDE. At last tested three different exits conditions of different vir tual environments. The simulation results show that this platform can thoroughly exhibit the movement of whole crowd,and can provide efficient data for the design of exits.
