Paper Abstract

This paper studies a three-dimensional non-contact attitude and deformation measuring system of the wind tunnel model. By projecting the single laser speckle on the measured three-dimensional space, it receives a random optical encoding. In addition, correlation search matching for collected image is conducted by matlab, the measurement data results of the existing PIV equipment are compared, and the spin binocular measurement system is employed to obtain the three-dimensional coordinate of the model. As a result, the feasibility of the system is verified. the author grasped the principle of 3D non-contact coding and recognition.
