Anipose is an open-source toolkit for robust, markerless 3D pose estimation of animal behavior from multiple camera views. It leverages the machine learning toolbox DeepLabCut to track keypoints in 2D, then triangulates across camera views to estimate 3D pose.

Check out the Anipose paper for more information.

The name Anipose comes from Animal Pose, but it also sounds like "any pose".
