Abstract
Conventional human motion tracking techniques based on optical systems reports important limitations for mobile applications (e.g. small spatial covering, poor environment flexibility). The present paper addresses a novel approach for optical motion tracking in open space. The measurement unit is transferred from its stationary basis onto a robotic moving platform. The platform design and limitations are described in the first place. It follows a comparative analysis of the measurement data accuracy for the stationary and mobile system. Post-processing techniques to convert acquired motion from the platform coordinate system into the ground’s absolute one are evaluated for the specific application of gait analysis.
