Markerless motion capture, unleashed.
Everything you need to set up the AR 51 system, capture in real time with Mocap Studio, and build with the Unity, Unreal, and streaming SDKs — no markers, no suits, no wearables.

AR 51 is a markerless motion-capture system: an array of machine-vision cameras feeds a GPU AI server that reconstructs full-body skeletons in real time — no markers, no suits, no wearables. You record and review takes in Mocap Studio, and stream the same live data straight into Unity, Unreal Engine, and live-production tools. This site is the developer and operator documentation: hardware and network setup, calibration, the desktop app, the SDKs, and the full SDK/API reference.
Machine-vision cameras + a GPU AI server reconstruct full-body skeletons live — no markers, suits, or wearables.
Track and identify multiple people at once, each driving its own character.
Stream live skeletons into Unity and Unreal Engine, with LiveLink, OpenXR, and Pico plugins for VR.
Send takes to FBX, C3D, and CSV — with biomechanical joint angles — for your DCC or analysis pipeline.
