Dynamic Synthesis Correction of Deviation for Aircraft Wing-fuselage Docking Assembly Based on Laser Tracker and Machine Vision

doi:10.3901/JME.2019.24.187

Abstract

Abstract: A method of dynamic synthesis correction of deviation error is proposed for aircraft wing-fuselage docking assembly by using laser tracker and vision with the object of fork-ear joint. In the stage of wing pose adjustment, the artificial fish swarm particle filter is used to track and estimate coordinates of points on the wing. Trajectory planning in combination with the locator inverse kinematics, dynamic modification model of the wing pose is built. In the stage of wing-fuselage docking, the characteristic parameters of the joint is dynamically detected to get joint position errors by machine vision. The error based on laser tracker and machine vision are fused and filtered, according to the principle of weighted least square of heterogeneous sensor information fusion. By this way, the models of dynamic monitoring of docking quality and comprehensive correction of docking deviation are also built. The experiments show that the proposed method can effectively improve quality of wing-fuselage docking assembly, and dynamic synthesis correction of deviation of wing-fuselage docking assembly is realized.
