An example of the use of OpenPose in a sport setting. Here, motion capture (MoCap) in 2D is used, for visualization purposes of the concept.
"OpenPose has represented the first real-time multi-person system to jointly detect human body, hand, facial, and foot keypoints (in total 135 keypoints) on single images."
OpenPose can perform MoCap in 3D for one person based on input from 2 or more different cameras. No markers are required. OpenPose can be used in real-time for direct feedback to coach and athlete.
