摘　　要：提出了一种基于位置/变迁Petri网结构的虚拟人行走动作模型。该模型首先根据人体特征和运动特征计算行走的时间和空间特征参数,进而根据实验数据,通过插值计算生成具体的人体运动,仿真模型框架是基于Petri网实现的,并以面向对象的方法封装了包括行走和爬行等周期性的行走动作。最后,设计并实现了一个仿真演示实例,结果验证了所提方法的可行性与有效性。A virtual human＇s walk action model based on place/transition Petri Net structure is described detailedly. Firstly, spatial and temporal parameters were generated form anthropometric characteristics and locomotion characteristics. Then, detailed human movement was interpolated from experimental data. Simulation structure was constructed on Petri Net, and several typical, periodical walk actions such as linear walk and crawl were realized with the OOP technologies. At last, a case study of virtual walking demonstration was designed and conducted. The results of simulation experiment indicate the effectiveness and usability of the proposed method.
