I. Introduction
Animal flight has the potential to transform current drone technology due to its superior manoeuvrability, energy efficiency, and load-carrying capacity [1]. However, these desirable features come at the cost of greater complexity, making understanding the kinematic and aerodynamic principles difficult. For the present work, image data from an array of 50 synchronized high-speed video cameras are to be used to reconstruct the detailed 3D flight kinematics of bats. The cameras of the array are used to capture the bats from several viewing directions while also covering a volume large enough for the animals to execute flight manoeuvres - the latter results in large numbers of images that do not capture the entire geometry of the bat.
