Unity-3D-based adaptive assembly guidance method and system

Abstract

The invention discloses a Unity-3D-based adaptive assembly guidance method and system. The method comprises the steps: S1, collecting geometric information and assembly relation information of a to-be-assembled body, constructing a physical model of the to-be-assembled body, and obtaining a spatial constraint relation between all parts in the physical model; S2, constructing a Petri network assembly process model according to the physical model of the to-be-assembled body and the spatial constraint relationship among the parts, and determining an assembly sequence of the to-be-assembled body;S3, importing an assembly process animation of the to-be-assembled body into a Unity 3D development platform, the assembly process animation being generated by the assembly sequence, the three-dimensional model of each part in the FBX format and 3ds Max; and S4, adding a control script to each part in the Unity 3D platform, realizing virtual assembly operation through input equipment, and providing text and animation prompts in the operation process. Therefore, the familiarity degree of assembly personnel to actual assembly work is improved, and the cost and the error rate are reduced.

Description

technical field [0001] The invention belongs to the technical field of virtual assembly, and more particularly relates to a method and system for guiding self-adaptive assembly based on Unity 3D. Background technique [0002] Assembly is an important part of the product design and manufacturing process, which has an important impact on product cost, quality, and reliability. It is particularly important for assembly staff to learn and master assembly operations. [0003] Although traditional computer-aided design tools or simulation tools provide simulated assembly operations, the scene is not intuitive enough, the assembly operations are not specific enough, and the assembly work in the real environment is not close enough. Workers' learning and familiarity with assembly work mainly rely on complex process manuals and Personal experience, the learning time is long and the efficiency is not high, and at the same time, the accuracy and correctness of the assembly work cannot ...
