Title
(EN) USER EQUIPMENT SENSOR CALIBRATION
(FR) ÉTALONNAGE DE CAPTEUR D'ÉQUIPEMENT UTILISATEUR
Abstract
(EN) A method for determining sensor calibration parameters includes: obtaining a plurality of sets of sensor measurement values, in a sensor coordinate system, of a sensor of a user equipment; and determining the sensor calibration parameters, based on a first portion of the plurality of sets of sensor measurement values corresponding to first times at which the user equipment is at rest and based on a second portion of the plurality of sets of sensor measurement values at least some of which correspond to second times at which the user equipment is in motion, such that application of the sensor calibration parameters to a selected set of the plurality of sets of sensor measurement values yields a calibrated set of calibrated sensor measurement values in a reference coordinate system.
(FR) Procédé de détermination de paramètres d'étalonnage de capteur consistant : à obtenir une pluralité d'ensembles de valeurs de mesure de capteur, dans un système de coordonnées de capteur, d'un capteur d'un équipement utilisateur ; et à déterminer les paramètres d'étalonnage de capteur, en fonction d'une première partie de la pluralité d'ensembles de valeurs de mesure de capteur correspondant à des premiers instants au cours desquels l'équipement utilisateur est au repos et en fonction d'une seconde partie de la pluralité d'ensembles de valeurs de mesure de capteur dont au moins certaines correspondent à des seconds instants au cours desquels l'équipement utilisateur est en déplacement, de telle sorte que l'application des paramètres d'étalonnage de capteur à un ensemble sélectionné de la pluralité d'ensembles de valeurs de mesure de capteur produise un ensemble étalonné de valeurs de mesure de capteur étalonnées dans un système de coordonnées de référence.
