摘　　要：人物运动规划对于表现动画主题方面有着突出的作用.当前手机短信3D动画自动生成系统只能进行单人运动规划,不具备人物交互运动规划自动生成这一功能.本文对此进行设计并实现,提出了一种基于三层动作识别和Kinesiology的交互规划方法,包括定性规划以及定量计算.采用基于语义网技术的规划方法结合动作知识建立交互动作本体库,通过情节推理,在定性规划阶段根据信息抽取的主题和模版来推出与短信内容相符的交互动作,最終在定量计算阶段确定动作执行双方的身体姿态以及规划交互双方的时空关系.经实验结果表明,本文所提出的规划能够使的动画中的人物完成较为复杂的交互动作.The planning for actions of characters plays a prominent role in displaying the animation theme. However, the automatic generation system of mobile phones 3D animation lacks of the planning for interactive actions of characters.This paper presents an interactive planning method based on the three-layer action identification and Kinesiology. This study mainly looked at two aspects： the qualitative planning and the quantitative calculation. First of all, semantic web technology was used to set up an interactive action ontology base. In the qualitative planning stage, the theme and template of information extraction were used to form interactive actions corresponding to the content of the short messages. Then, in the quantitative calculation stage, determine the physical posture of both parties performing actions and to plan the temporal and spatial relationship between the two parties of interactions. The experimental results show that the proposed scheme can make the characters in the animation perform more complex interactive actions.
