摘要
基于智能主体理论,提出了虚拟人的结构体系。虚拟人的结构体系包括感觉模块、知觉模块、规划模块、行为模块、行动模块、数据库模块、知识库模块、情绪模块、内部变量模块、运动控制模块。这些模块集成为一个整体。本文着重介绍规划模块和行为模块的功能。虚拟人的行为用产生式规则来描述,每条产生式规则具有不同的优先度,可以在不同的行为之间建立合成运算,采用抑制增益系数和疲劳系数来表现行为的时序特征。最后,在微机上实现了一个基于本文模型的虚拟人行为动画系统。
The architecture of virtual human is presented based on agent theory in this paper. The architecture of virtual human includes sense module, perception module, plan module, behavior module, action module, database module, knowledge base module, emotion module, internal variable module, and motor control module. These modules are integrated as a system. This paper mainly introduces function of plan module and behavior module. The behavior of virtual human is expressed with productive rules, each productive rule has different prior degree, synthetic operation can be set up among different behaviors, and inhibitory gain coefficient and fatigue coefficient is used to represent sequential feature of behavior. At last, a behavioral animation system based on the model in this paper is realized on PC.
