Topic: Data-driven Markerless Motion Capture System for Clinical Applications


Movement assessments in clinical settings are typically performed by clinicians based on observations and simple motion measurement instruments. High precision motion capture (mocap) systems that based on infrared cameras and reflective markers are widely used in the entertainment industry and sports science domain, but it is never adopted as a standard measurement method in clinical movement assessment, because of its labour-intensive workflow. This talk introduces a Markerless Motion Capture system which uses regular video cameras and eliminates the need for reflective markers on the human body. The current prototype has achieved the accuracy level of a high-grade commercial mocap system by a novel machine learning algorithm with automatic data postprocessing, hence making the system affordable and suitable to be used in clinical workflow.
