Uporaba optičnega 3-D merilnega sistema Aramis v dinamični antropometriji

This paper presents a study on the possible application of the Aramis optical 3D measuring system for analysing dynamic deformations of the human body in motion. A methodology for the use of Aramis in the field of dynamic anthropometry is presented for the first time in this study. Five body movements were analysed on three female test subjects. Based on the surface deformation results, a set of ten characteristic body measurements, relevant for garment design and construction, were identified, analysed and compared to reference values obtained using laser 3D body scanning technology. Changes in measurement dimensions during particular movements were determined in relation to initial measurements in a static standing position, where the greatest body measure deformation recorded was a 37% increase in back width during arm-forward movement and a 23% elongation of the posterior lower body length during forward bending. A comparative analysis of the results indicated a high level of precision of measurements obtained using the Aramis system, which achieved mean absolute errors of less than 3 mm and relative errors of less than 3%, thus emphasising the ability to monitor and analyse surface deformations of the body throughout entire movements and not just in final body positions, as is the case with the use of 3D body scanning technology. The proposed measurement methodology from this study offers valuable data for the development of garment model design, material selection and clothing pattern construction according to the requirements of dynamic anthropometry.
