Camera Optical Markerless Motion Capture Solution – Virdyn YanDong | Real-Time Full Body, Hands, Face
Adopting a completely wearable-free design, the YanDong system requires no motion capture suits, helmets, or physical markers throughout the entire capturing process. It utilizes multi-camera synchronous video acquisition to perform all-round tracking of the human body, delicate fingers, and facial expressions. Powered by advanced artificial intelligence algorithms, the system conducts real-time AI human detection and 3D human reconstruction, followed by precise AI skeleton motion solving. Combined with forward and inverse kinematics calculation logic, the system further optimizes raw motion data through a temporal transformer network, achieving intelligent motion correction and frame-to-frame smoothing for stable, jitter-free, and highly natural motion output.
