面向虚拟维修训练的自抓取虚拟手交互行为构建

Self-fetching virtual hand interaction behavior building with virtual maintenance training

针对当前维护训练模拟器(MTD)不能很好地向受训者展示飞机维修过程中的具体维修动作的问题,构建一种自抓取的虚拟手与相应的交互行为,以提高机务培训质量。通过分析维修的基本动作要素,定义与构建基于蒙皮骨骼的虚拟手动作库;在场景漫游阶段,实时获取视角位置来驱动虚拟手运动,以减轻场景漫游下的虚拟手控制负荷;在具体维修操作阶段,利用所提的交互行为算法,将虚拟手的位置自调节与骨骼动画osgCal相结合,通过调取动作库中的相应动作来完成具体的维修任务。实验结果表明,该方法能较好地展现具体的维修操作,对于虚拟维修训练具有良好的可用性。

Focusing on the problem that the current maintenance training device(MTD)can't perfectly reflects the specific maintenance actions during the aircraft maintenance for trainees,this paper established a self-fetching virtual hand and the interaction behaviors to improve the training quality.By analyzing the basic elements of maintenance operations to define and built the virtual hand operation library that based on skinned mesh.In the scene roaming stage,in order to reduce the control load,it drove the virtual hand by the viewpoint position which was acquired in real time.In the specific maintenance operation stage,it used the interactive behavior algorithm to combine the position self-adjustment of the virtual hand with the skeleton animation osgCal,by calling the relevant actions in the action library to complete the specific maintenance tasks.The experimental results show that the proposed method can reflect the specific maintenance operations and have a good usability for virtual maintenance training.
