What is AR 51
AR 51 is a markerless motion-capture system. It tracks people and objects in real time using infrared cameras and computer vision — no markers, no suits, no wearables — and streams skeletal motion into game engines, broadcast graphics, and analysis tools.
It runs in controlled studios and at full-scale live venues, and operates across lighting conditions from direct sunlight to darkness.
What you can do with it
- Capture motion of one or many people simultaneously, plus tracked objects (e.g. balls in sports).
- Stream skeletons in real time into Unity and Unreal (incl. LiveLink and Disguise RenderStream).
- Record and export to FBX, C3D, NPZ, SMPL-X, glTF, CSV, and more.
- Analyze movement with built-in biomechanical visualization.
