Title
(EN) DETERMINING MOTION ZONES IN A SPACE TRAVERSED BY WIRELESS SIGNALS
(FR) DÉTERMINATION DE ZONES DE MOUVEMENT DANS UN ESPACE TRAVERSÉ PAR DES SIGNAUX SANS FIL
Abstract
(EN) In a general aspect, a method for determining motion zones in a space traversed by wireless signals. In some aspects, the method includes obtaining, over a time frame, sets of channel response data based on wireless signals communicated over wireless links through a space between wireless communication devices. A time series of statistical parameters is generated for each wireless link based on a respective set of channel response data. The method additionally includes determining a plurality of motion zones in the space based on changes in the time series of statistical parameters for each wireless link. Sets of motion-zone parameters are generated that characterize respective motion zones of the plurality of motion zones. The method further includes storing, in a database of a motion detection system, the plurality of motion zones and sets of motion-zone parameters. The sets of motion-zone parameters are used to identify one of the plurality of motion zones based on a motion event detected by the motion detection system.
(FR) Un aspect général de l'invention concerne un procédé de détermination de zones de mouvement dans un espace traversé par des signaux sans fil. Selon certains aspects, le procédé consiste à obtenir, sur une trame temporelle, des ensembles de données de réponse de canal en fonction de signaux sans fil communiqués sur des liaisons sans fil dans un espace entre des dispositifs de communication sans fil. Une série chronologique de paramètres statistiques est générée pour chaque liaison sans fil en fonction d'un ensemble respectif de données de réponse de canal. Le procédé consiste en outre à déterminer une pluralité de zones de mouvement dans l'espace en fonction de changements dans la série chronologique de paramètres statistiques pour chaque liaison sans fil. Des ensembles de paramètres de zone de mouvement sont générés, ces derniers caractérisant les zones de mouvement respectives de la pluralité de zones de mouvement. Le procédé consiste en outre à mémoriser, dans une base de données d'un système de détection de mouvement, la pluralité de zones de mouvement et des ensembles de paramètres de zone de mouvement. Les ensembles de paramètres de zone de mouvement sont utilisés pour identifier une zone de la pluralité de zones de mouvement en fonction d'un événement de mouvement détecté par le système de détection de mouvement.
