An Assembly Operation Perception Model in Augmented Reality Environment
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.
