基于空间增强现实的辅助装配系统研究

Research on Auxiliary Assembly System Based on Spatial Augmented Reality

人工装配是飞机装配过程中的重要环节,但是由于装配零件种类多、位置复杂、装配工艺繁多等问题导致了装配效率低、装配质量难以保证,严重影响了飞机整体装配的质量和效率。通过对空间增强现实辅助装配应用中跟踪配准技术、投影仪–相机标定技术分析,以及在三维机器视觉技术研究的基础上,开发了具有引导信息编辑、待投影工件定位、引导信息投影功能的全流程投影引导辅助装配系统,通过在飞机工件表面投影辅助装配信息的方式简化复杂的装配流程。从验证试验中可以看出,采用该系统可以显著提高装配效率和装配质量,大幅度缩短装配周期。

Manual assembly is an important link in the aircraft assembly process.However,due to the variety of assembly parts,complex assembly locations,and numerous assembly processes,the assembly efficiency is low and the assembly quality is difficult to guarantee,which severely affects the quality and efficiency of the overall aircraft assembly.Based on the analysis of tracking registration technology and projector-camera calibration technology in spatial augmented reality auxiliary assembly applications,and on the basis of 3D machine vision technology research,this paper develops a full-process projection-guided auxiliary assembly system with functions of projection information edit,workpiece positioning and guidance information projection.By projecting auxiliary assembly information on the surface of aircraft workpieces,the system can simplify complex assembly processes.It can be seen from the verification experiment that the use of this system can significantly improve the assembly efficiency and assembly quality,and greatly shorten the assembly cycle.
