VALIDATION OF A MARKERLESS MOTION CAPTURE SYSTEM FOR THE CALCULATION OF LOWER EXTREMITY KINEMATICS

INTRODUCTION New methods for the capture of human movement motivated by technological advances aiming to use non-intrusive or markerless motion capture [1] offer the potential to address some of the limitations of current methods for human gait analysis and open the door for new opportunities for the study of normal and pathological motion. While theoretical studies [2,3] showed that human kinematics can be accurately estimated in a virtual environment, these methods have not been tested with laboratory data. The purpose of this study was to evaluate the accuracy of human body kinematics extracted from experimental data using a visual hull markerless motion capture system.
