RESCUE: Crowd Evacuation Simulation via Controlling SDM-United Characters

  • 采用感知-决策-运动框架,融合自适应社会力模型与个性化步态控制
  • 支持动态路径规划与个体差异化行为,可在不平地形上运行
  • 提供部件级受力可视化,助力疏散分析,适合安全演练与城市规划

人群疏散模拟对提升公共安全至关重要,尤其在逼真的虚拟环境中。现有主流模型忽视了疏散过程中的复杂人类行为,如行人碰撞、人际互动,以及地形类型或个体体型带来的行为差异,导致仿真结果与现实脱节。本文基于人脑的感知-决策-运动(SDM)流程,提出一种实时3D人群疏散模拟框架,集成3D自适应社会力模型(SFM)决策机制与个性化步态控制运动模块。该框架支持多智能体并行移动,具备动态群体感知能力,适用于多种场景。此外,引入部件级受力可视化技术,辅助疏散分析。实验表明,本框架能实现每个代理在疏散全程中的动态轨迹规划与个性化行为表现,兼容不平整地形。视觉效果更逼真可信,为人群模拟提供更深入洞察。代码已开源:http://cic.tju.edu.cn/faculty/likun/projects/RESCUE。

原文摘要 · Abstract (English)

Crowd evacuation simulation is critical for enhancing public safety, and demanded for realistic virtual environments. Current mainstream evacuation models overlook the complex human behaviors that occur during evacuation, such as pedestrian collisions, interpersonal interactions, and variations in behavior influenced by terrain types or individual body shapes. This results in the failure to accurately simulate the escape of people in the real world. In this paper, aligned with the sensory-decision-motor (SDM) flow of the human brain, we propose a real-time 3D crowd evacuation simulation framework that integrates a 3D-adaptive SFM (Social Force Model) Decision Mechanism and a Personalized Gait Control Motor. This framework allows multiple agents to move in parallel and is suitable for various scenarios, with dynamic crowd awareness. Additionally, we introduce Part-level Force Visualization to assist in evacuation analysis. Experimental results demonstrate that our framework supports dynamic trajectory planning and personalized behavior for each agent throughout the evacuation process, and is compatible with uneven terrain. Visually, our method generates evacuation results that are more realistic and plausible, providing enhanced insights for crowd simulation.
