Complex easy-to-deform cabin butt joint visual assembly auxiliary method based on augmented reality

Abstract

The invention discloses an augmented reality-based visual assembly assisting method for butt joint of complex and easily-deformed cabin sections, and relates to the field of intelligent assembly. The method comprises the following steps of: constructing a virtual assembly simulation environment by utilizing an actually measured cabin section three-dimensional model, and detecting a fit clearance and an interference state; performing information interaction with a virtual assembly simulation environment through a standard communication interface protocol by adopting an assembly path intelligent optimization algorithm to complete optimal assembly path planning; and superposing the assembly guide path and an actual assembly path obtained by visual detection into an augmented reality environment after virtual-real registration in the forms of a 3D image, a path deviation value and the like, so as to realize a visual intelligent assembly auxiliary function. According to the invention, the assembly problems of frequent jamming, dislocation and the like in the butt joint process of complex and easily-deformed cabin sections can be solved, the dependence on experience and skills of operators is reduced, and the assembly efficiency and the one-time assembly success rate are greatly improved.

Description

technical field [0001] The invention relates to the field of intelligent assembly, in particular to an augmented reality-based visual assembly auxiliary method for the docking of complex and easily deformable cabin sections. Background technique [0002] Assembly is an important link in the manufacture of high-end equipment such as aerospace, and the difficulty in the docking and assembly of complex and deformable cabins has become one of the bottlenecks that restricts the improvement of high-end equipment manufacturing efficiency. Aerospace equipment generally adopts embedded multi-step positioning assembly interface to ensure connection reliability and improve force characteristics and sealing performance. The cabin section has the characteristics of large size and weight, high matching precision, and many thin-walled shells. Affected by gravity and complex manufacturing process, its embedded over-positioning assembly interface is prone to deformation, and the datum relat...
