(54) English Title: TOPOLOGICAL AND MOTION MEASURING TOOL
(54) French Title: INSTRUMENT SERVANT A MESURER LA TOPOLOGIE ET LE MOUVEMENT

Abstracts

English Abstract




A position, orientation, shape and motion measuring tool is provided in the
form of a flexible substrate with bend and twist sensors distributed along its
surface at known intervals. A ribbon-type substrate is preferred. The
geometric configuration of the substrate is calculated from inter-referencing
the locations and orientations of the sensors based upon the detected bend and
twist values. Suitable applications include motion capture for humans for use
in animation, six degree of freedom input to a computer, profile measurement
and location tracking within a large, singularity-free working space.


French Abstract

L'invention concerne un instrument servant à mesurer la position, l'orientation, la forme et le mouvement. Ledit instrument se présente sous forme d'un substrat flexible, muni de capteurs de courbure et de torsion, lesquels sont répartis le long de la surface dudit substrat à des intervalles préétablis. Un substrat de type ruban est préférable. La configuration géométrique du substrat est calculée à partir des références comparées des emplacements et des orientations des capteurs en fonction des valeurs de courbure et de torsion détectées. Des applications possibles sont les suivantes: saisie du mouvement à des fins d'animation, entrée de six degrés de liberté dans un ordinateur et mesure du profil et repérage d'emplacements dans un espace de travail important ne présentant pas de singularités.
