Welcome to the page associated with the research work titled 3D Pose Estimation of Bats in the Wild. Here we make the 3D graphics model used in our work publicly available. Additionally, we are also sharing a calibrated, multi-view, infrared dataset, showing bats flying in the wild.


Graphics Model:
To preview what our 3D graphics model looks like you can take a look here. Note: the preview will prompt you to install a webplayer based on the Unity3D game engine, and you may need to refresh the page a few times to get it to show. Alternatively, you can see a preview in our paper on page 2.

Our 3D graphics model, Tadarida_Brasiliensis_Bat_Model.blend, works with the freely available 3D modeling tool Blender. To manipulate and interact with our bat model, modeled after the species Tadarida Brasiliensis, you will need to download Blender and learn the basics of the interface. Many introductory tutorials can be found on YouTube, which is largely how I learned to use Blender. With some basics of Blender you should be able to open the bat model and manipulate it, e.g translation, rotation. We also provide a script bat_model_controller.py which will allow you to set the wing angles of the bat programatically. The wings of the bat are modeled by a large chain of bones. There is also some code which can take in a list of quaternions (rotations) and create a rendering of the bat for each rotation. This graphics model can be used as is, or serve as an initial model for a modified and improved version. Please contact me at breslav at bu dot edu with any questions comments.
