APPARATUS AND METHOD FOR ESIMATING ORIENTATION USING PATTERN RECOGNIION

摘要

The present invention discloses an apparatus for estimating a pedestrian direction by using pattern recognition and a method for estimating a direction by using this apparatus. An embodiment of the present invention includes a database that stores behavior pattern information for user behavior pattern determination and direction pattern information for estimating a user movement direction; a sensor unit that senses acceleration information, three-axis terrestrial magnetism information, and rotation information from a behavior of the moving user; a behavior pattern determination unit that determines one behavior pattern corresponding to the behavior of the moving user in the behavior pattern information stored in the database based on the sensing result; and a direction estimation unit that estimates the user movement direction by comparing the three-axis terrestrial magnetism information and the rotation information with respect to the determined behavior pattern to the direction pattern information stored in the database.
