20.500.12556/RUL-125756 Three-dimensional measurements of bodies in motion based on multiple-laser-plane triangulation This paper presents laser-based, three-dimensional (3D) measuring applications involving three different bodies in motion: a knee joint during leg motion (1) , thoraco - abdominal and back deformation during breathing (2) and the shape of a foot during walking (3) . The first (1) setup is based on a commercial sensor Kinect, whereas the second (2) and the third (3) are based on custom - developed, multiple - line, triangulation measuring systems. Special attention was given to the color - modulation principle and the selection of the proper optical components. Based on the calibration, the accuracy of the system is 1.4 mm (1), 0.7 mm (2) and 0.5 mm (3 ), while the measuring range is 900 x 700 x 600 mm (1), 400 x 600 x 500 mm (2) and 400 x 160 x 180 mm (3). The camera frame rate for each setup is 30 Hz (1), 25 Hz (2) and 30 Hz (3). All the systems were evaluated in vivo on adult volunteers. The presented measuring systems are capable of real - time measurements , while enabling a precise and nonintrusive analysis of shape deformation, which has a lot of potential in clinical diagnosis, patient assistance or the development of new shoe models. laser triangulation 3D measurement bodies in motion color - modulation shape deformation laserska triangulacija 3D meritve telesa v gibanju barvna modulacija deformacija oblike true false true Angleški jezik Slovenski jezik Članek v reviji 2021-04-06 22:58:46 2021-04-06 22:58:54 2022-09-05 03:52:28 0000-00-00 00:00:00 2015 0 0 Str. 53-61 N° 2 Vol. 38 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.946:681.518.52(045) 0254-0770 14172955 RAZ_Poredos_Primoz_2015.pdf RAZ_Poredos_Primoz_2015.pdf 1 1A8B6AE92171C27758B14C853313CC8A ed0f7d32221bd42b08087f45308ed657cb49f4d77a4e53f901baec3143a193b8 c9479bdd-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141618 Fakulteta za strojništvo 0 0 0
