An airframe butt joint attitude-adjusting method meeting stringer reference alignment and straightness requirements includes the steps: measuring end face reference points and linear guide rail reference points of a fixed airframe section and an attitude-adjusting airframe section and coordinates of the position of an attitude-adjusting system three-dimensional positioner connector connected with the attitude-adjusting airframe section by a laser tracker; building airframe end face reference point matching and straightness matching target functions, and accordingly building a mathematic model for airframe butt joint attitude-adjusting calculation; performing iterative calculation for the airframe butt attitude-adjusting model by a Gauss-Newton method to obtain coordinates of optimal butt joint positions of the attitude-adjusting airframe section and the fixed airframe section and obtain a transformational matrix from an initial position to a target position; calculating the coordinates of the target position of an attitude-adjusting system three-dimensional positioner connector connected with the attitude-adjusting airframe section according to the obtained transformational matrix, and butting the attitude-adjusting airframe section and the fixed airframe section by controlling movement of the attitude-adjusting system three-dimensional positioner from the initial position to the target position.
