Accuracy of a novel marker tracking approach based on the low-cost Microsoft Kinect v2 sensor

Marker-based optical motion capture systems and wearable inertial sensors have been employed widely in clinical gait analysis [1]. In the most favourable conditions, optical marker-based tracking can provide an overall accuracy of 63  ± 5 μm [2]. However, these systems are not always practical in the clinical setting, given the substantial setup costs and space requirements [3]. Wearable devices based on inertial sensors are low-cost, but are subject to position measurement errors as a consequence of acceleration integra tion [1].
