1. A method for determining position of a mobile device with at least one imaging device, comprising: obtaining, using the at least one imaging device of the mobile device, at least one image including a stationary pattern of pixels; searching through a database of pixel patterns for a pixel pattern that most closely matches the pattern of pixels in the obtained at least one image; retrieving from the database as a result of the searching, positional information about one of the pixel patterns that is deemed to most closely match the pattern of pixels in the obtained at least one image; and analyzing, using a processor of the mobile device, in combination with the retrieved positional information, relative size of or a size differential between the most closely matching pixel pattern and the pattern of pixels in the obtained at least one image to derive positional information about a position of the mobile device.
