Validation of enhanced kinect sensor based motion capturing for gait assessment

Identification of the foot events.
Foot events (black crosses) based on the ankle trajectories, here exemplified using the Kinect skeleton averaged across all sensors. Using the same procedure foot events were extracted from the VICON data. Top: Snapshots of the body posture during walking, bottom: ankle position of the left (red) and right (blue) foot in walking direction.
