Estimation to Use the Stick Figure of Kinect® Version 2 for Digital Anthropometry
In this paper we examine the possibility to use the integrated stick figure and their joint positions of Microsoft® Kinect® version 2 for digital measurement of human body dimensions. Manual anthropometric measurement data and the indirect parameter calculation based on Kinect® joints were compared for selected human body dimensions. This paper takes a closer look at the length measurements of body height and arm span.
15 female participants took part in a subject test. Participants stood frontal to the Kinect® in two different stages (feet together and slightly apart; both with and without shoes) and in three different poses. Each parameter was analysed by three different algorithms based on the Kinect® joint data.
For determination of body height, the indirect parameter calculation seems to be a possible replacement of the direct manual anthropometric measurement, if the accuracy claim is low. We observed deviations between the values derived from Kinect® data and the direct anthropometric values up to 5 cm. Arm span data as well shows linear trends, but deviations are higher. Multivariate analyses seem to be necessary.
