摘　　要：目前人群疏散的行为动画应用较少,根本原因在于需要设置大量参数,从而需要大量的手工交互。针对此问题,提出了一种速度场驱动的人群宏观行为表示方法。方法包括人群运动实验、典型速度场提取、交互式人群速度场设计和人群行为动画合成等4个步骤。以该算法为核心开发了三维虚拟人群仿真系统,实验结果表明该方法交互工作量小,仿真结果逼真,具有广泛的应用面。Synthesizing a realistic animation of crowd behavior in a virtual environment often requires executing cumbersome manual interaction and setting a large number of empirical pa- rameters. Aimed at this tedious problem, this paper presems the macroscopic behavior of crowd representation based on a ve- locity field-driven method, which contests four steps： capturing video in real scene, typical pedestrian velocity field extraction, interactive design for velocity field crowd, and real-time anima tion synthesis on crowd behavior. 3D evacuation simulation re- sults showed that the method with little interactive workload can afford realistic simulations and has wide range of application surface.
