Title (EN) SYSTEMS AND METHODS FOR ESTIMATING THE GEOGRAPHIC LOCATION AT WHICH IMAGE DATA WAS CAPTURED
(FR) SYSTÈMES ET PROCÉDÉS D'ESTIMATION DE L'EMPLACEMENT GÉOGRAPHIQUE AUQUEL DES DONNÉES D'IMAGE ONT ÉTÉ CAPTURÉES
Abstract:
(EN) In some embodiments, a system and method for estimating the geographical location at which image data was captured with a camera identifies matching feature points between the captured images, estimates a pose of the camera during the image capture from the feature points, performs geometric reconstruction of a scene in the images using the estimated pose of the camera to obtain a reconstructed scene, and compares the reconstructed scene to overhead images of known geographical origin to identify potential matches
(FR) Conformément à certains modes de réalisation, l'invention concerne un système et un procédé d'estimation de l'emplacement géographique auquel des données d'image ont été capturées à l'aide d'un appareil photographique. Lesdits système et procédé identifient des points caractéristiques correspondant entre les images capturées, estiment une pose de l'appareil photographique pendant la capture d'image à partir des points caractéristiques, effectuent une reconstruction géométrique d'une scène dans les images à l'aide de la pose estimée de l'appareil photographique pour obtenir une scène reconstruite, et comparent la scène reconstruite à des images en vue de dessus d'une origine géographique connue pour identifier des correspondances potentielles.
