Abstract
(EN)
This positioning system is provided with: a local position acquisition unit that continuously acquires local positional information being relative positional information of a communication terminal; a storage unit that stores map data; a positioning unit that, on the basis of image data captured in the communication terminal and the map data stored in the storage unit, estimates global positional information of the communication terminal at the time of imaging in the communication terminal: and a position derivation unit that, on the basis of a change in the local positional information acquired by the local position acquisition unit, estimates a movement amount from the time of imaging in the communication terminal, and on the basis of the movement amount, corrects the global positional information estimated by the positioning unit, thereby deriving positional information of the communication terminal with consideration given to the movement amount.

La présente invention concerne un système de positionnement comprenant : une unité d'acquisition de position locale qui acquiert en continu des informations de position locale qui sont des informations de position relative d'un terminal de communication ; une unité de stockage qui stocke des données cartographiques ; une unité de positionnement qui, sur la base de données d'image capturées dans le terminal de communication et des données cartographiques stockées dans l'unité de stockage, estime des informations de position globale du terminal de communication au moment de l'imagerie dans le terminal de communication : et une unité de déduction de position qui, sur la base d'un changement dans les informations de position locale acquises par l'unité d'acquisition de position locale, estime une quantité de mouvement à partir du moment d'imagerie dans le terminal de communication, et sur la base de la quantité de mouvement, corrige les informations de position globale estimées par l'unité de positionnement, obtenant ainsi des informations de position du terminal de communication en tenant compte de la quantité de mouvement.
