摘要:
Methods and systems for map generation for location and navigation with user sharing/social networking may comprise determining a position of a wireless communication device (WCD) and capturing images of the surroundings of the WCD. Data associated with objects in the surroundings of said WCD may be extracted from the captured images, positions of the objects may be determined, and the determined positions and the data may then be uploaded to a database. The elements may comprise structural and/or textual features in the surroundings of the WCD. The position of the WCD may be determined utilizing sensors in the WCD to measure a distance from a last determined or known position. The sensors may comprise a pedometer, an altimeter, a camera, and/or a compass. The positions of the extracted elements may be determined utilizing known optical characteristics of a camera in the WCD.
