Method of constructing artificial mark for autonomous driving, apparatus and method of determining position of intelligent system using artificial mark and intelligent system employing the same

Abstract

A method for constructing an artificial mark for autonomous driving of an intelligent system, an apparatus and method for determining the location of an intelligent system using the artificial mark, and an intelligent system employing the same. The apparatus and method for determining the location of an intelligent system includes a projective invariant calculator which calculates a projective invariant of an artificial mark detected from an image taken for a driving place; a search unit which stores a database of indices according to a combination of colors of polygons included in the artificial mark, projective invariants of the artificial marks, and global location information of the artificial marks in the driving place, and searches the database by the calculated projective invariant for obtaining the global location information of the detected artificial mark; and a position information analyzer which analyzes the position of the intelligent system by using the global location information of the detected artificial mark and location information between the intelligent system and the detected artificial mark.
