Abstract: The system for indoor navigation includes a global coordinate generator for dividing an indoor space, extracting a feature point where images photographed by cameras installed at predetermined locations overlap, and generating a global coordinate of the feature point, a database for storing information about the image and global coordinate of the feature point generated by the global coordinate generator, and a mobile device for extracting a feature point from an image of a surrounding environment photographed by a camera thereof, comparing the extracted feature point with the feature point stored in the database, and estimating location and direction thereof by using a global coordinate of a coincident feature point.
