METHOD FOR EXTRACTING KINETIC MODEL FROM 3D GEOMETRIC MODEL

摘要

The present invention relates to a method for extracting a movement model from a 3D geometric model, which comprises: a first step of dividing a 3D assembly model into a plurality of parts in order to search a contact surface between first and second parts contacted to each other among the parts; a second step of distinguishing whether the first and second parts contacted to each other among the parts are a cylinder type contact or not; a third step of generating a central axis of a cylinder in case of the cylinder type contact; a fourth step of determining whether the first and second parts are a prismatic joint or a revolute joint by using the central axis, wherein in the fourth step, the first and second parts are determined as the revolute joint if the collision of the first and second parts is generated in the two directions by moving the first and second parts along the central axis, and the first and second parts are determined as the prismatic joint if the collision is generated only in one direction or not generated.
