Three-dimensional movement measurement for the wing of a flying airplane

The movement parameters of a wing of a flying airplane are important for its design, analysis and life-estimation, while the three-dimensional measurement of these parameters is a difficult task. A measurement setup is proposed as well as its corresponding calibration and image processing algorithms to fulfill the task. The calibration methods for the camera system on both ground condition and air condition are developed. We present a new method of location of 3D straight line through plane-plane intersection. The results show that the 3D measurement accuracy in the difficult air condition can be better than 1 mm.
