摘　　要：研究了虚拟维修系统的场景和对象的交互控制问题,为了维修人员的安全,提高设备维修效率,根据EON虚拟现实开发软件,设计了TPO视点变化函数,根据对象的装配/拆卸行为建立视点变化模型,场景及对象的运动导航操作方便;根据武器装备分级维修的特点,采用二维交互设备,设计了对象6自由度运动交互控制方法,提出的节点逻辑分离算法,能够在系统运行状态下解除节点间的隶属关系,解决已分离节点与父节点的运动关联问题,装配/拆卸行为真实感强。实际试验结果表明,所设计的虚拟维修训练系统和虚拟测试系统,对导航方法和交互操作,结果满足要求,为设计提供了依据。Methods of roam about the scene and interactive control about virtual object in system of virtual maintain system was researched on. A viewpoint transformation function called TPO was designed,based on virtual reality software of EON. In terms of action of equipment assemble/disassemble,the model of viewpoint transformation can be design,and the operation of roam about and navigation of object were convenient. According to the characteristics of weapons maintains in grades,the control means of 6 freedom of virtual object were designed,by using two-dimensional interactive device. A logical detach algorithm of nodes was put forward,it can free relationship of administrative subordination between nodes,and the problem of motion interconnection between detached node and father node was solved. Based on these methods,training system of virtual maintains and virtual test systems were constructed. Practical application shows that the model of navigation is reasonable and interactive operation is really true.
