2、bly occur during the wind tunnel test. This elastic deformation will seriously affect the aerodynamic characteristics of test model, result in the unexpected results of the wind tunnel tests, and affect the vehicle's

3、 design and performance evaluation. Therefore, for this situation, the main purpose of this thesis is to measure the elastic deformation of the wing of wind tunnel test model during the test, and then use it to correct t

4、he model’s wind tunnel test data. In this thesis, a binocular VMD(Videgrammetric Model Deformation) measurement system has been designed for the specific environment of a transonic wind tunnel’s complete model test secti

5、on. The system layout the specific style markers upon the surface of test model’s fuselage and wing, and use two high-resolution video cameras to capture the test images via the observation windows at the top of test sec

6、tion; the system measure the markers’ three-dimensional coordinates on the test model by using the principle of binocular stereo vision, and calculate the wing’s aerodynamic load deformation by comparing the markers’ coo

7、rdinates during the wind tunnel test. This thesis mainly completes the following tasks in the process of design and implementation the binocular VMD measurement system: 1) Complete the design of the hardware structure, s

8、oftware structure , and wind tunnel testing process of binocular VMD measurement system for the specific environment in a transonic wind tunnel; 2) Implement the key technology of binocular VMD measurement, including fea

9、ture recognition and localization, marker tracking, stereo matching, field calibration and three-dimensional reconstruction; 3) Design and implement a ground test platform to validate the performance of the designed bino

10、cular VMD measurement system. The results of ground experiment show that: the system has high accuracy and fast computing speed, has achieved the requirement of real-time measurement. Keywords: Wind Tunnel Test, Model D
