Visual positioning system

Abstract

Systems and methods for image-based self-localization of an image capture device, include receiving a query image of an undetermined location of the image and comparing the query image to a set of geotagged reference images to determine a location of the query image. The system and method may alternatively compare a series of query images to reference images or portions of feature vectors generated from said query images and reference images to determine the closest query image in the series to respective reference images. The set of geotagged reference images may include a sequence of previously obtained reference images of a route, each reference image corresponding to a known geolocation. The geolocation of the user may be determined based on the location of the query image within the set. Ambient conditions of the images may be used to improve comparison of a query image to reference images. Segment and/or abstractions of cell images may be used to reduce computational and/or communications resources.
