Research of the Assembly Process in Augmented Reality Mechanical Assembly Environment

Analyzed the process of virtual and real assembling parts in Augmented Reality assembly. Focused on： the assembly styles of virtual and real parts, the planning of movement path, the collision detection of assembly and the output of feedback force. Achieved the relative movement and assembly by planning the movement path of virtual parts and adopting the style of six-degree-of-freedom movement; A novel collision detection method - shell test was proposed, and a collision detection algorithm was defined through virtually constructing the points and areas of parts collision; Using the Falcon device, the coordinate of virtual parts could be picked and the feedback force could be outputted. To some extent, the experimental test results show that this shell test is a general theory which can achieve the collision detection of virtual and real parts and output of force feedback.
