Theia

Theia3D uses artificial intelligence to deliver markerless motion capture, tracking 124 keypoints to build precise 3D skeletal models directly from standard video, removing the time, cost, and setup constraints of traditional marker-based systems. At Target3D World, we stock the full Theia3D software, which lets researchers, clinicians, and coaches capture human movement in real-world environments rather than being confined to a marker-calibrated lab space, making it well suited to sports performance analysis, gait research, and clinical movement assessment. Because there are no markers or suits required, subjects can move naturally and be filmed with standard video cameras, dramatically reducing setup time between sessions and making repeat testing far more practical for busy clinics and research labs. Theia3D's output integrates with established biomechanics analysis tools, giving researchers a fast, markerless route from raw video straight through to joint angles, kinematics, and full skeletal modelling. Whether you're running sports performance testing, clinical gait analysis, or biomechanics research in the field, Theia3D gives you accurate, markerless motion capture without the constraints of a traditional optical system.
