Theia Markerless
Theia Markerless is a Motion Capture & Performance company founded in 2018 and based in Kingston, Canada.
Theia Markerless is a Kingston, Ontario company founded in 2018, spun out of a research project at C-Motion after co-founder Marcus Brown began developing the technology during his mechanical-engineering studies at Queen's University. Its Theia3D software uses deep-learning pose estimation on synchronized multi-camera video to capture human movement without markers or suits, with subjects in everyday clothing. Marketed for biomechanics, clinical assessment, and sports performance, it is used by research institutions and labs including Queen's University, Stanford, the Mayo Clinic, Driveline Baseball, and the US Olympic Committee.
Brings lab-grade accuracy to markerless mocap, validated against marker-based systems and widely cited in biomechanics research — the rigorous end of the avatars-and-motion stack.
