Abstract
The present disclosure relates to methods, to a mobile device and to a server for support of augmented reality on the mobile device. The mobile device acquires a current image of its environment. The mobile device determines its orientation and its location by comparing the current image with reference image information related to an estimated location of the mobile device. The mobile device may provide information about new, modified or missing reference image features, for a given location, to a server. The server may then update a corresponding reference image feature in a local database.
