虚拟装备仿真训练系统中的一种行为建模方法

A Method of Behavior Modeling in VR Training System

首先分析了虚拟现实系统的自主性特点,要使得虚拟环境中物体具备自主性需要建立相应物体的其物理行为模型,对其物理行为进行仿真,从而确定虚拟环境中物体的状态。在构建特定的VR系统时,人作为参与者必须按照一定的规则和虚拟环境中的物体进行交互,尤其在虚拟装备仿真训练系统中,建立相应的操作行为模型以确定环境中物体行为和反应。本文提出了一种基于规则的行为建模方法,已成功应用于某大型武器装备虚拟仿真训练系统,提高了系统的沉浸感和交互性。

One of hot research issues of VR is to develop training system. To obtain the physical behavior of object in VE, we need to build its behavior model, thereby improving the autonomy of VR system. As participator, human interacting with objects in VE must obey some rules especially in VR training system. It needs building the behavior model of the participator to obtain the reaction of objects in VE. In this article, a behavior modeling method based on expert rule is found, and successfully enhances the immersive and interactive of one equipment virtual training system.
