(FR) APPAREIL, SYSTÈME ET PROCÉDÉ DE LOCALISATION À DISTANCE D'UN MARQUEUR AU MOYEN DE CHAMPS MAGNÉTIQUES.
Abstract
(EN) A marker for remote localisation in a medium, the marker including a magnetic field sensor configured to measure three different magnetic fields at three different respective times in three dimensions at a marker location in the medium, wherein the marker is configured to generate measurement data representing the measured magnetic fields for determining the marker location.
(FR) Marqueur pour la localisation à distance dans un milieu, qui comporte un capteur de champ magnétique conçu pour mesurer trois champs magnétiques différents à trois instants différents respectifs dans trois dimensions à l'emplacement du marqueur dans le milieu, ledit marqueur étant conçu pour générer des données de mesure représentant les champs magnétiques mesurés pour déterminer l'emplacement dudit marqueur.
