In the wind tunnel experiment, high-speed airflow will cause bending deformation and torsion deformation in the wing. This paper proposes a method for measuring the wing bending and torsion deformation based on the error correction model. First, the camera calibration method based on photogrammetry is used to obtain the camera distortion parameter with the use of digital image correlation method to locate and track the distortion-free pixel coordinates of fluorescent points. Then an airflow calibration plate with coordinate axis system is established based on photogrammetry technology, and the airflow coordinate axis calibration plate is used to calibrate the external parameters of the camera and obtain the Y coordinate of the fluorescent marker point on the wing. Finally, the three-dimensional reconstruction models of the single and binocular measurement systems and the error correction model for bending and torsion deformation are established with the known Y-axis constraints of the marker point. When the angle of attack is 0° horizontally, the bending and torsional deformation of the wing in the blowing state is calculated as the reference state with the model. After experimental verification, the measurement error of wing torsional deformation proposed in this article is less than 0. 01°, and the measurement error of wing bending deformation is less than 0. 15 mm / m. This method can provide reliable and robust experimental data for aircraft design.
