NSTC Research Projects

Development of AI-powered markerless stereophotogrammetric system for accurate 3D skeletal motion capture, analysis, and MR-based data visualisation, and applications to lower limb malalignment (2025-2027)
— Skeletal malalignment requires precise, non-invasive monitoring during growth. This project builds MIT3D, an AI markerless motion capture system integrating stereophotogrammetry, CT/MRI-trained bone modeling, physics-based kinetics, and MR visualization. Over three years, it reconstructs subject-specific skeletons and quantifies alignment and joint loading changes in adolescents undergoing guided growth surgery.
PI: Prof. Tung-Wu Lu, National Taiwan University

Artefact-free knee joint movement assessment using motion capture
(NSTC-Bilateral Collaborative Research Project, 2024-2026)
— Leveraging advanced motion analysis, 3D dynamic X-ray, and biomechanical modeling, this project optimizes STA reduction to generate precise population-based knee kinematics, enhancing clinical skin-marker gait analysis.
PIs:
Prof. Tung-Wu Lu, National Taiwan University
Prof. Raphaël Dumas, Gustave Eiffel University

Developing a novel measurement system based on stereo-photogrammetric digital image correlation and machine learning trained with 3D fluoroscopy data for 3D foot/ankle skeletal biomechanics and surface morphological changes during locomotion: applications to different foot types and ankle arthrodesis (2024-2026)
— Foot–ankle function depends on complex skeletal motion and plantar deformation during locomotion, yet current tools cannot capture these dynamics in vivo. This project builds an AI-driven DIC–fluoroscopy system to measure 3D kinematics and strain, evaluates effects of arch height and arthrodesis, and integrates ML with motion capture for precise clinical biomechanics.
PI: Prof. Tung-Wu Lu, National Taiwan University

Application of Dynamic Imaging Technology to Assess Lower Back Load During Manual Lifting Tasks in Workers
— During high-load lifting, excessive lumbar burden increases the risk of WMSDs. This study applies 2D image recognition and 3D reconstruction to estimate L5/S1 joint moments, comparing vision-based results with optical motion capture. The approach enables real-time identification of hazardous postures and evaluation of lumbar-load risk across diverse lifting conditions.
