High-speed surface reconstruction of a flying bird using structured light

摘要: ABSTRACT Birds fly effectively and maneuver nimbly by dynamically changing the shape of their wings during each wingbeat. These changes have yet to be quantified automatically at high temporal spatial resolution. Therefore, we developed a custom 3D surface reconstruction method, which uses high-speed camera identify spatially encoded binary striped patterns that are projected on flying bird. This non-invasive structured-light method allows automated stand-alone frame can extended multiple views. We demonstrate this new technique reconstructing dorsal parrotlet wing 3200 frames s−1 flapping flight. From analyze key parameters such as twist angle attack distribution. While our ‘single-shot’ algorithm is demonstrated quantifying dynamic bird, it generally applicable moving animals, plants deforming objects.
