P2.53  Thursday, Jan. 5  3D Reconstruction and Analysis of Bat Flight Maneuvers from Sparse Multiple View Video BERGOU, AJ*; SWARTZ, S; BREUER, K; TAUBIN, G; Brown University attila_bergou@brown.edu

We present a novel framework for the 3D reconstruction and analysis of complex flight maneuvers performed by bats.  By incorporating biomechanical and geometric knowledge about bats into an articulated model, we are able to recover the time varying posture of freely flying bats from sparse multiple view high speed video. Our method scales easily to multiple views, elegantly handles missing and occluded markers, and has a versatility in the type and complexity of the tracking model. We apply this tracking method, in conjunction with a simulation framework we developed, to analyze how bats perform complex aerial rotations during landing and takeoff.
