Measuring the Wing Kinematics of a Moth (Helicoverpa Armigera) by a Two-Dimensional Fringe Projection Method

We describe a two-dimensional (2-D) fringe projection method, projecting two groups of comb-fringe patterns with high intensity and sharpness onto the flapping wings of a moth (Helicoverpa armigera) from two directions. The images of distorted fringes are caught by two high speed cameras from two orthogonal views. By three-dimensional reconstruction of the wing, we obtain the wing kinematics of the moth including the flapping angle, torsion angle and camber deformation.
