Abstract: Disclosed is an augmented reality content in-situ authoring method and apparatus. In an augmented reality content in-situ authoring method, a reference object or an augmented target object to be augmented may be selected from a camera preview image of a real world, a two-dimensional (2D) plane region may be recognized based on the selected reference object or the augmented target object and then a virtual 3D space may be constructed and divided based on the 2D plane region, and augmented reality content may be augmented through the divided space.

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.
