Comparative study of the two versions of the Microsoft Kinect$^{\rm TM}$ sensor in regard to the analysis of human motion
This work addresses the need for reliable motion capture technology in fields like healthcare or sports, but it is incremental as it focuses on comparing existing sensor versions without introducing new methods.
The study compared two versions of the Microsoft Kinect sensor for human motion analysis, finding differences in output quantities and noting the original sensor's unsuitability for high-precision applications, necessitating validation of the upgraded sensor with a marker-based system.
The present paper is part of a broader programme, exploring the possibility of involving the Microsoft Kinect$^{\rm TM}$ sensor in the analysis of human motion. In this study, the output obtained from the two available versions of this sensor is critically examined. We demonstrate that the two outputs differ in regard to the variation of the physical quantities involved in the modelling of the human motion. As the original sensor has been found unsuitable for applications requiring high precision, the observed differences in the output of the two sensors call for the validation of the upgraded sensor on the basis of a marker-based system.
