Title (EN) POSITION ESTIMATION APPARATUS AND POSITION ESTIMATION METHOD
(FR) APPAREIL D'ESTIMATION DE POSITION ET PROCÉDÉ D'ESTIMATION DE POSITION
(JA) 位置推定装置及び位置推定方法
Abstract:
(EN) A position estimation apparatus (10) is provided with: receivers (110a, 110b, 110c) for measuring the reception strength of radio waves emitted from a moving body (20), the receivers (110a, 110b, 110c) being provided in mutually different known positions; and a computing device (230) for performing, successively for each receiver (110a, 110b, 110c), processing for updating an estimated position of the moving body (20) on the basis of the reception strength measured by a single receiver among the receivers (110a, 110b, 110c) so as to approach a presence circle having the receiver at the center thereof and having a distance based on the reception strength as the radius thereof.
(FR) L'invention concerne un appareil d'estimation de position (10) comprenant : des récepteurs (110a, 110b, 110c) permettant de mesurer l'intensité de réception d'ondes radioélectriques émises depuis un corps mobile (20), les récepteurs (110a, 110b, 110c) étant situés dans des positions connues mutuellement différentes ; et un dispositif informatique (230) permettant d'effectuer, successivement pour chaque récepteur (110a, 110b, 110c), un traitement afin de mettre à jour une position estimée du corps mobile (20) en fonction de l'intensité de réception mesurée par un seul récepteur parmi les récepteurs (110a, 110b, 110c) de manière à s'approcher d'un cercle de présence ayant le récepteur pour centre et ayant une distance fondée sur l'intensité de réception pour rayon.
(JA) 位置推定装置(10)は、互いに異なる既知の位置に設置され、移動体(20)から発せられる電波の受信強度を測定する受信器(110a、110b、110c)と、受信器(110a、110b、110c)のうちの1つの受信器で測定された受信強度に基づき、移動体(20)の推定位置を、前記受信器を中心とし前記受信強度に基づく距離を半径とする存在円に近づくように更新する処理を、受信器(110a、110b、110c)の各々について逐次行う計算器(230)と、を備える。
