摘　　要：在研究流演算理论及其实现语言FLUX的基础上,将流演算与虚拟现实技术中的虚拟人相结合,提出了一个基于目标驱动的、有自主行动能力的虚拟人模型。设计了动作检测模块,同时使用了动作队列,根据动作检测的结果来决定是否执行下一个动作,使虚拟人可以针对动态变化的虚拟环境进行有效的行动规划。利用此模型可以快速构建出一个在不完全可知的虚拟环境中通过感知到的有限信息进行实时的、自主行动推理的智能虚拟人。最后,实现了办公室场景中智能虚拟人行动推理系统。This paper introduced the target-driven virtual humans model having autonomous behaviors ability, and realized it by combining fluent calculus with virtual humans in virtual reality, based on the research on the theory of fluent calculus and its implementation language FLUX. In addition, designed the action detection model to judge whether the next action could be performed according to its detecting results by using action queue to store the sequences of actions, making virtual human can make effective plans in dynamic changed virtual environment. By implementing this model, intelligent virtual humans can be constructed quickly which could reason about action automatically and real-time using the limited information acquired from sensor in an incomplete, dynamic environment by themselves for any given goals. Finally, action planning system for intelligent virtual human of office scenario is achieved.
