Title (EN) POSITION MEASUREMENT DEVICE AND INDOOR POSITIONING SYSTEM
(FR) DISPOSITIF DE MESURE DE POSITION ET SYSTÈME DE POSITIONNEMENT INTÉRIEUR
(JA) 位置測定装置および屋内測位システム
Abstract:
(EN) Provided are a position measurement device and an indoor positioning system capable of performing highly accurate indoor positioning. The position measurement device (2) comprises: a movable imaging unit (6); and a current position calculation unit (10) that calculates the current position of the imaging unit (6) in a building on the basis of information indicating the installation position of an own-position transmitter (1) provided in the building, the information being extracted from an image transmitted by optical wireless communication from the own-position transmitter (1) and captured by the imaging unit (6), and also on the basis of the relative direction of the own-position transmitter (1) calculated from the image captured by the imaging unit (6).
(FR) L'invention concerne un dispositif de mesure de position et un système de positionnement intérieur capables de réaliser un positionnement intérieur hautement précis. Le dispositif de mesure de position (2) comprend : une unité d'imagerie mobile (6) ; et une unité de calcul de position actuelle (10) qui calcule la position actuelle de l'unité d'imagerie (6) dans un bâtiment sur la base d'informations indiquant la position d'installation d'un émetteur de position propre (1) disposé dans le bâtiment, les informations étant extraites d'une image transmise par une communication optique sans fil à partir de l'émetteur de position propre (1) et capturée par l'unité d'imagerie (6), et également sur la base de la direction relative de l'émetteur de position propre (1) calculée à partir de l'image capturée par l'unité d'imagerie (6).
(JA) 精度の高い屋内測位を行うことができる位置測定装置および屋内測位システムを提供する。この発明に係る位置測定装置(2)は、移動可能な撮像部(6)と、建物内に設けられた自己位置送信機(1)から光無線通信により発信され撮像部(6)で撮像された映像から抽出された自己位置送信機(1)の設置位置を示す情報および撮像部(6)で撮像された映像から算出された自己位置送信機(1)の相対的な方向に基づいて、建物内における撮像部(6)の現在位置を算出する現在位置算出部(10)と、を備える。
