During the automatic docking assembly of aircraft wing-fuselage, using monocular camera or dual-camera to monitor the docking stage of the fork-ear will result in an incomplete identification of the fork-ear pose-position and an inaccurate description of the deviation in the intersection holes’ position coordinates. To address this, a quality inspection and error correction method is proposed for the fork-ear docking assembly based on multi-camera stereo vision. Initially, a multi-camera stereo vision detection system is established to inspect the quality of fork-ear docking assembly. Subsequently, a spatial position solution mathematical model of the fork-ear feature points is developed, and a spatial pose determination mathematical model of fork-ear is established by utilised the elliptical cone. Finally, an enhanced artificial fish swarm particle filter algorithm is proposed to track and estimate the coordinate of the fork-ear feature points. An adaptive weighted fusion algorithm is employed to fuse the detection data from the multi-camera and the laser tracker, and a wing pose-position fine-tuning error correction model is constructed. Experimental results demonstrate that the method enhances the effect of the assembly quality inspection and effectively improves the wing-fuselage docking assembly accuracy of the fork-ear type aircraft.

Cette analyse qui s'inscrit dans le cadre d'un projet de recherche AFFISA (Airbus Front Fuselage Innovative Structural Approaches) a pour objectif d'étudier la faisabilité d'un moyen d'essais permettant de tester des structures de fuselage double courbure représentatif avion (pointe avant et cône arrière d'avion). En effet, aucun moyen de ce type n'existe actuellement supporté par des analyses éléments-finis, le comportement de la structure soumise à des efforts mécaniques et de pression a été étudié. Notre attention s'est principalement focalisée sur le chargement en compression (et traction) qui pose certains problèmes du fait de la spécificité de la double courbure. Cette étude se terminera par la proposition de deux concepts de moyen d'essais brevetés.
