Title (EN) HIGHLY ACCURATE WIRELESS POSITIONING METHOD AND DEVICE

(KO) 고정확도의 무선 측위 방법 및 장치
Abstract:
(EN) The present invention relates to a highly accurate wireless positioning method and device whereby: the strength of at least one signal transmitted from at least one fixed node is measured; the relative position of a mobile node is estimated; a variation pattern of at least one signal strength according to the relative change in position of the mobile node across multiple time points is generated from the at least one signal strength and the relative position of the mobile node; and the absolute position of the mobile node is estimated on the basis of a comparison between the variation pattern of the at least one signal strength and a map of a signal strength distribution pattern at an area in which the mobile node is positioned. Thus, the position of the mobile node may be accurately estimated even when a wireless environment changes, and the position of the mobile node may be accurately estimated across a wide area by using a wireless signal exhibiting almost no change in signal strength.
(FR) La présente invention concerne un procédé et un dispositif de positionnement sans fil très précis tels que : l'intensité d'au moins un signal émis à partir d'au moins un nœud fixe est mesurée; la position relative d'un nœud mobile est estimée; un motif de variation d'au moins une intensité de signal en fonction du changement relatif de positon du nœud mobile sur de multiples points temporels est généré à partir de ladite intensité de signal et de la position relative du nœud mobile; et la position absolue du nœud mobile est estimée sur la base d'une comparaison entre le motif de variation de ladite intensité de signal et une carte d'un motif de répartition d'intensité de signal au niveau d'une zone dans laquelle est positionné le nœud mobile. Ainsi, la position du nœud mobile peut être estimée avec précision même lorsqu'un environnement sans fil change, et la position du nœud mobile peut être estimée avec précision sur une large zone en utilisant un signal sans fil ne présentant presque aucun changement d'intensité du signal.
(KO) 고정확도의 무선 측위 방법 및 장치에 관한 것으로, 적어도 하나의 고정 노드로부터 송출된 적어도 하나의 신호의 세기를 측정하고, 이동 노드의 상대 위치를 추정하고, 적어도 하나의 신호 세기와 이동 노드의 상대 위치로부터 복수의 시점에 걸친 이동 노드의 위치의 상대적인 변화에 따른 적어도 하나의 신호 세기의 변화 패턴을 생성하고, 적어도 하나의 신호 세기의 변화 패턴과 이동 노드가 위치하는 지역에서의 신호 세기의 분포 패턴 형태의 지도와의 비교에 기초하여 이동 노드의 절대 위치를 추정함으로써 무선 환경의 변화에도 이동 노드의 위치를 정확하게 추정할 수 있으면서 넓은 지역에 걸쳐 신호 세기의 변화가 거의 없는 무선 신호를 이용하여 이동 노드의 위치를 정확하게 추정할 수 있다.
