Abstract

The invention discloses a digital three-dimensional part virtual assembly method based on assembly points, and relates to the digital three-dimensional part virtual assembly technology. The method comprises the following steps: setting one point (assembly point) or a plurality of points (assembly points) on the digital three-dimensional part (or a certain relative position in space), and during virtual assembly, moving a part model in a virtual environment by an operator through input equipment, so that the assembly points on the part model are overlapped with the assembly points of a target part to finish the accurate assembly of the part.

Description

technical field [0001] The patent of the present invention relates to virtual assembly technology, in particular to a method for virtual assembly of digital three-dimensional components based on assembly points. Background technique [0002] In the actual assembly environment, people realize the guidance and perception of the movement of parts through the cooperation of vision and touch, so as to realize the precise assembly of parts. Since the virtual environment lacks various physical constraints and perception capabilities that exist in the real environment, the precise positioning of components mainly depends on geometric constraints during the virtual assembly process. [0003] At present, the establishment of digital 3D component models and the application of virtual assembly are mainly based on CAD systems. Virtual assembly is mainly based on the constraints between geometric primitives after the completion of component modeling Parallel, coincident, tangent, etc. of...
