摘　　要：目前公安执法动作训练过程中存在突发状况无法充分模拟,多种执法场景难以同时快速搭建,受训人员易造成身体损伤等问题,虚拟仿真训练可有效满足训练科学化、实战化的要求。虚拟执法人员是执法动作虚拟训练中的重要组成部分,为了实现更佳的沉浸效果,满足实战化需求,提出了一种用于肢体运动交互的方法,搭建了肢体交互骨架模型,分析了关节的运动规则,设计了运动算法,实现了运动仿真系统的交互结构,最终利用3ds MAX、Multigen Creator、Vega和C语言编程实现了虚拟人运动仿真控制,为虚拟人在公安执法动作训练应用方面提供了一条有效途径。At present, there are problems in the process of police law enforcement action training, such as the sudden situation cannot be fully simulated, it is difficult to build multiple enforcement scenarios at the same timeand the trainees are prone to physical injury. Virtual simulation training can effectively meet the requirements of scientific and practical training. Virtual law enforcement personnel is an important part of virtual training of law enforcement actions. In order to achieve a better immersive effect and meet the actual needs, this paper presented a method for limb motion interaction. The skeleton model of limb interaction was established, the motion rules of the model were specified, the motion algorithm was studied, and the architecture of the interaction system was constructed. Finally, the motion simulation control of virtual humanswas realized using 3 ds max, Multigen Creator, Vega, and C programming language. It provided an effective way for the application of virtual humans in the training of public security law enforcement actions.
