摘要： 如何构建行为可信的虚拟人是自主人群仿真中的关键问题。根据马斯洛的动机理论，建立自主人群的行为模型，该模型利用产生式规则，将刺激、动机和行为集成在一起。引入有限状态机描述刺激和动机的关系，虚拟人通过虚拟视觉感知刺激，虚拟人之间的局部碰撞检测通过排斥力控制。在微机上实现原型系统，实验结果表明，该模型能够较好地模拟自主群体行为。

Abstract: The simulation research on autonomous crowd behavior is a challenging subject, and how to build a virtual human with credible behavior is the key technology. Based on Maslow’s motivation theorem, a behavior model of autonomous crowd is set up. The model can integrate stimuli, motivation and behavior together with productive rulers. A Finite State Machine(FSM) is introduced to express the relation between stimuli and motivation. A virtual human can perceive a stimulus on virtual vision, and the local collision among virtual human is controlled by repulsive force. A prototype system is realized on PC, and the result shows that the model can closely simulate autonomous crowd behavior.

Key words: crowd, motivation, Finite State Machine(FSM), animation simulation, autonomous behavior
