SIMBioSys (SwRI Markerless Biomechanics system) automatically produces an accurate model and analysis of a subject’s musculoskeletal biomechanics with greater ease and similar performance to marker-based motion capture systems. Marker-based motion capture is the standard within biomechanics research to analyze local and full-body movement patterns. However, marker-based systems are often confined to controlled settings, like laboratories, given the limitations of the hardware (i.e., specific infrared cameras and numerous reflective markers), accessibility (i.e., knowledge of anatomical landmarks for marker placement), and time (i.e., placing complex marker sets and processing marker data). SIMBioSys addresses these limitations by leveraging artificial intelligence to identify anatomical points in synchronized videos of a subject using commercial-off-the-shelf video cameras.
