An Assembly Operation Perception Model in Augmented Reality Environment

现有的自然虚拟装配操作交互模型对双手协同操作和单步操作工作量的表达存在不足,针对这个问题,提出增强现实装配操作感知模型,实现机械装配操作参数化表达。提出基于装配运动特征的虚拟物体位姿计算方法,建立模型的真实手部元素与被操作虚拟物体元素的运动关联,满足模型对虚拟物体位姿求解的需求。提出基于模型元素的模型关键状态计算方法,满足模型运行需求。开发了应用案例,实验表明,模型可表达五种常见装配操作,满足装配培训需求。

The existing virtual assembly system’s natural assembly operation and interaction models have defects for expressing the workload of two-handed cooperative operation and single-step operation.To solve this problem,an assembly operation perception model in its augmented reality environment is proposed.The model can parametrically express the mechanical assembly operation.A virtual object pose calculation method based on assembly motion characteristics is proposed.The method is based on the motion correlation between the elements of the model,namely the real hand and the manipulated virtual object.The calculation methods of the model's key states based on its elements are proposed to meet the requirements of the model's operation.An application case is developed.The experimental results show that the assembly operation perception model can express five common assembly operations and satisfy the requirements for assembly training.
