Abstract
(EN)
A method 400 of automatically assigning segments of trajectories 110, 120, 130 to floors of a building 100 comprises receiving 801 data concerning a trajectory from a mobile device152, the data comprising height data and ambient signal data; segmenting 802 the trajectory using the height data, such that a change in the height data marks an end region of a segment. A change in the height data between adjacent segments is referred to as a height link. The method further comprises calculating 803 similarity values for pairs of segments based on the ambient signal data; using the similarity values, grouping 804 the segments into a plurality of groups based on the ambient signal data; checking 805 for errors in the grouping using the height links; accepting 808a the grouping if the checking does not identify any errors, or re-running 807 the grouping if it does; and, once the grouping is accepted, assigning 809 the groups to corresponding floors.

Procédé 400 d'attribution automatique de segments de trajectoires 110, 120, 130 à des étages d'un bâtiment 100 consistant à recevoir 801 des données concernant une trajectoire à partir d'un dispositif mobile 152, les données comprenant des données de hauteur et des données de signal ambiant ; segmenter 802 la trajectoire à l'aide des données de hauteur, de telle sorte qu'un changement des données de hauteur marque une région d'extrémité d'un segment. Un changement des données de hauteur entre des segments adjacents est appelé liaison de hauteur. Le procédé consiste en outre à calculer 803 des valeurs de similarité pour des paires de segments sur la base des données de signal ambiant ; utiliser les valeurs de similarité, grouper 804 les segments en une pluralité de groupes sur la base des données de signal ambiant ; vérifier 805 les erreurs dans le groupement à l'aide des liaisons de hauteur ; accepter 808a le regroupement si la vérification n'identifie aucune erreur, ou re-exécuter 807 le regroupement s'il y en a ; et, une fois que le groupement a été accepté, attribuer 809 les groupes à des étages correspondants.
