摘　　要：基于流演算的行为推理方法提出了五元组智能体模型,通过该模型在虚拟环境中建立语义实体,虚拟人作为一种特殊的语义实体,通过与环境对象的语义交互,感知虚拟环境。虚拟人能够根据当前的状态和预先的规划自主完成追逐行为,为动态虚拟环境中的目标追击问题提供一种智能化仿真方法。以语义交互的方式实现虚拟人的各种感知仿真,建立虚拟人智能体的推理结构和层次化的行为方式。在Unity引擎上以有限状态机方式给出了应用实例,验证了该方法的可行性和有效性。This paper presents a five-tuple agent model based on fluent calculus, which is used to establish semantic entity in virtual environment. Virtual human, as a special semantic entity, can perceive the virtual environment by the semantic interaction with environment object. Virtual human can accomplish the pursuit behavior independently according to the current state and pre-planning, which provides an intelligent simulation method for the target pursuit problem in dynamic virtual environment. The virtual human perception simulation is realized by semantic interaction, and the reasoning structure and hierarchical behavior of virtual human agent are established. An application example is given on the Unity engine in the form of finite state machine, which verifies the feasibility and effectiveness of this method.
