A deep learning model estimates human ground reaction dynamics from motion capture data by integrating physics-based supervision, reducing dependency on force plates and achieving an 18% improvement in vertical GRF estimation accuracy and a 38% decrease in simulated root position error.
Key insights
- Integrating physics-derived supervision from motion capture data can effectively complement or replace direct force plate measurements, enhancing model robustness and physical plausibility, especially with incomplete sensor data.
- A balanced weighting of direct sensor data and physics-informed supervision in the loss function is crucial for optimal deep learning model performance.
- Physics-based simulation with optimized PD control parameters can accurately infer reactive forces necessary to reproduce the global translational dynamics observed in human motion capture.
