System and method for mersuring location in wireless communication terminal, method for collecting fingerprint information in wireless communication terminal, fingerprint server and method for providing location using the same

摘要

PURPOSE: A location measuring device of a wireless communication terminal, a location measuring method, a finger print information collecting method, a finger print server, and a location providing method thereof are provided to measure a location by using characteristic point information extracted from an image captured by a camera module embedded in the wireless communication terminal. CONSTITUTION: An azimuth measuring unit(152) measures azimuth facing a wireless communication terminal. Finger print local database(154) stores the address of a beacon device for measuring points, a signal strength, and finger print information including the azimuth. A location measuring unit(153) measures a location based on the finger print information stored in the finger print local database and the beacon device of a beacon signal received from a signal strength measuring unit.
