Abstract

Un procédé et un dispositif servent à déterminer et à mesurer des contours corporels à détecter, notamment des systèmes articulaires en trois dimensions et pour mesurer le profil, la courbe ou les contours en trois dimensions. A cet effet, des capteurs électriques détectent une position de déplacement à partir d'un point zéro sélectionnable comme point de référence et une position angulaire, détectée pour chaque position de déplacement détectée, d'un capteur dans l'espace par rapport à chaque point de la colonne vertébrale ou d'un autre contour corporel à explorer. Une position dans l'espace est déterminée et les ensembles de données (points de déplacement/valeurs angulaires) sont établis. Le dispositif correspondant (100) comporte un bâti (10) pourvu d'un dispositif de mesure angulaire qui mesure l'angle de rotation autour d'un axe et se présente sous la forme d'un système oscillant à plomb (12). Le bâti (10) sur lequel est disposé le système oscillant à plomb (12) comporte un mécanisme de déplacement (11) qui coopère avec au moins un capteur électrique de mesure de déplacement (13).
