A locator bracket hybrid attitude positioning platform is adopted, and a digital positioning method for aircraft thin-walled flexible large parts is proposed. Firstly, the singular value decomposition (SVD) computer wing pose is used to obtain the motion state of each axis of the positioner through kinematic inverse solution. Secondly, according to the characteristics of the large deformation of the aircraft, a method for establishing the coordinate system of the aircraft components to eliminate the pose error is proposed to achieve fast and high-precision attitude adjustment. Finally, the method is applied to the attitude of the aircraft wing, and the measured attitude accuracy meets the assembly requirements.
