3D shape acquisition of fast-moving objects is an emerging area with many potential applications. This paper presents a novel application of 3D acquisition for studying the dynamic external morphology of live bats in flight. The 3D acquisition technique is based on binocular stereo vision. Two high-speed (500 fps) calibrated machine vision cameras are employed to capture intensity images from the bats simultaneously, and 3D shape information of the bats are derived from the stereo video recording. Since the high-speed stereo vision system and the bat dynamic morphology study application are both novel, it was unknown to what extent the system could perform 3D acquisition of the bats shapes. We carried out experiments to evaluate the performance of the system using artificial objects in various controlled conditions, and the knowledge gained helped us deploy the system in the on-site data acquisition. Our preliminary analysis of the real data demonstrates the feasibility of gathering 3D dynamic measurements on bats bodies from a few selected feature points and the possibility of recovering dense 3D shapes of bat heads from the stereo video data acquired. Issues are revealed in the 3D shape recovery, most notably related to motion blur and occlusion.
