Abstract
In the flapping flight study, it is important to know the mechanics of the flapping wings to assist research in different fields such as biology and robotics. In this research, we propose a novel dynamic 3D strain measurement framework for robotic flapping wings. We set up a superfast 3D shape measurement platform with defocused binary stripe illumination to perform high-resolution dynamic 3D reconstruction. Then, we developed a novel point tracking algorithm based on geodesic computation. Finally, we performed dense 3D strain measurement by examining the curvature changes of tracked points. Experiments will demonstrate the success of our technology.
