  • Method for correcting control surface angle measurements in single viewpoint photogrammetry
    Patent number: 7130725
    Abstract: A method of determining a corrected control surface angle for use in single viewpoint photogrammetry to correct control surface angle measurements affected by wing bending. First and second visual targets are spaced apart from one another on a control surface of an aircraft wing. The targets are positioned at a semispan distance along the aircraft wing. A reference target separation distance is determined using single viewpoint photogrammetry for a “wind off” condition. An apparent target separation distance is then computed for “wind on.” The difference between the reference and apparent target separation distances is minimized by re-computing the single viewpoint photogrammetric solution for incrementally changed values of target semispan distances. A final single viewpoint photogrammetric solution is then generated that uses the corrected semispan distance that produced the minimized difference between the reference and apparent target separation distances.
