Abstract: front page image
(EN)The present invention relates to a test node-based wireless positioning method and a device thereof, the method comprising the steps of: mapping and storing the number and position coordinates of anchor nodes, which are within a set distance from a test node, for each of a plurality of test nodes set at uniform intervals in a space formed by a plurality of anchor nodes; acquiring each position coordinate of the anchor nodes, which are within the set distance from a random node to be positioned; comparing each of the acquired position coordinates of the anchor nodes and the position coordinates of the anchor nodes mapped on the test nodes, so as to select the test nodes of which the number of position coordinates coinciding with the anchor nodes is greater than a threshold; and estimating the position of a random node by using the position coordinates of the selected test nodes. According to the present invention, wireless positioning performance can be improved and more reliable high precision positioning information can be provided.
(FR)La présente invention concerne un procédé de positionnement sans fil à base de nœud d'essai et un dispositif associé, le procédé comprenant les étapes de : mise en correspondance et stockage du nombre et des coordonnées de position de nœuds d'ancrage, qui sont à une distance définie d'un nœud d'essai, pour chacun d'une pluralité de nœuds d'essai installés à des intervalles uniformes dans un espace formé d'une pluralité de nœuds d'ancrage; acquisition de chaque coordonnée de position des nœuds d'ancrage, qui sont au plus à la distance définie d'un nœud aléatoire devant être positionné; comparaison de chacune des coordonnées de position des nœuds d'ancrage acquises et des coordonnées de position des nœuds d'ancrage mises en correspondance sur les nœuds d'essai, de manière à sélectionner les nœuds d'essai dont le nombre de coordonnées de position coïncidant avec les nœuds d'ancrage est supérieur à un seuil; et estimation de la position d'un nœud aléatoire au moyen des coordonnées de position des nœuds d'essai sélectionnés. Selon la présente invention, les performances de positionnement sans fil peuvent être améliorées et des informations de positionnement de haute précision plus fiables peuvent être obtenues.
(KO)본 발명은 테스트 노드 기반의 무선 측위 방법 및 그 장치에 관한 것으로, 복수의 앵커 노드들이 형성하는 공간상에 균일 간격으로 설정되는 복수의 테스트 노드 각각을 대상으로, 테스트 노드로부터 설정 거리 내에 있는 앵커 노드의 개수 및 위치 좌표를 매핑하여 저장하는 단계, 측위 대상이 되는 임의 노드로부터 상기 설정 거리 내에 있는 앵커 노드의 위치 좌표를 각각 획득하는 단계, 획득한 각각의 앵커 노드의 위치 좌표와 테스트 노드에 매핑된 앵커 노드의 위치 좌표를 비교하여, 앵커 노드의 위치 좌표가 일치하는 개수가 임계치 이상인 테스트 노드들을 선택하는 단계, 및 선택한 테스트 노드들의 위치 좌표를 이용하여 임의 노드의 위치를 추정하는 단계를 포함한다. 이에 따르면, 무선 측위 성능을 향상시킬 수 있으며 더욱 신뢰성 있는 고정밀의 측위 정보를 제공할 수 있다.
