1. A system for providing localization of a mobile electronic device within an environment, the system comprising:
- at least one server in communication with the mobile electronic device, the at least one server adapted to receive input data from at least one picture and at least one accelerometer measurement from the mobile electronic device;
a memory database in communication with at least one server, the memory database storing at least one 3-dimensional map of the environment; and
a localization module adapted to be executed by the at least one server, the localization module providing localization to the mobile electronic device based on the input data from the at least one picture, the at least one accelerometer measurement and the at least one 3-dimensional map of the environment;
wherein the 3-dimensional map includes a database of 3-dimensional feature points; and
wherein the localization module provides localization by matching 2-dimensional feature points from the at least one picture with the 3-dimensional feature points of the 3-dimensional map.

Abstract
A system and method for providing localization of a mobile electronic device within an environment includes at least one server in communication with the mobile electronic device. The at least one server is adapted to receive at least one picture and at least one accelerometer measurement from the mobile electronic device. The at least one server includes a localization module that provides localization to the mobile electronic device based on the at least one picture, the at least one accelerometer measurement and on at least one 3-dimensional map of the environment.
