Abstract
(EN)
The present invention simply and appropriately updates a reference image in position estimation using an image. A position estimation system 10 is provided with: a reference image database 11 in which a reference image and information indicating a position are stored in association with each other; an acquisition unit 12 which acquires an estimation image to be subjected to position estimation; an estimation unit 13 which compares the reference image and the estimation image with each other to estimate a position related to the estimation image from the information indicating the position associated with the reference image, and calculates reliability of the estimated position; and an update unit 14 which updates, on the basis of the reliability, the reference image using the estimation image.

La présente invention met à jour de manière simple et appropriée une image de référence dans une estimation de position à l'aide d'une image. Un système d'estimation de position (10) comprend : une base de données d'images de référence (11) dans laquelle une image de référence et des informations indiquant une position sont stockées en association les unes avec les autres; une unité d'acquisition (12) qui acquiert une image d'estimation à soumettre à une estimation de position; une unité d'estimation (13) qui compare l'image de référence et l'image d'estimation l'une à l'autre pour estimer une position relative à l'image d'estimation à partir des informations indiquant la position associée à l'image de référence, et calcule la fiabilité de la position estimée; et une unité de mise à jour (14) qui met à jour, sur la base de la fiabilité, l'image de référence à l'aide de l'image d'estimation.
