Abstract:
Methods and systems for location determination using structural visual information may comprise receiving global navigation satellite system (GNSS) signals in a wireless device (WD) for determining a first position of the WD. One ore more images of a structure or structures near the WD may be captured and a position may be determined based on a comparison of the structures in the images to structures in a stored database. The database may be pre-stored based on a known future location of a user of the WD. The database may be downloaded and stored when insufficient GNSS signals are present. The database may comprise a plurality of images or may comprise video of structures. A distance from the structures may be determined based on known optical properties of a camera in the WD, and may be used to determine an accurate location based on the images.
