Abstract
Disclosed herein is a localization system and method to recognize the location of an autonomous mobile platform. In order to recognize the location of the autonomous mobile platform, a beacon (three-dimensional structure) having a recognizable image pattern is disposed at a location desired by a user, the mobile platform which knows image pattern information of the beacon photographs the image of the beacon and finds and analyzes a pattern to be recognized from the photographed image. A relative distance and a relative angle of the mobile platform are computed using the analysis of the pattern such that the location of the mobile platform is accurately recognized.

23. A localization method comprising:
-
photographing a beacon having a recognizable image pattern and recognizing the image pattern of the beacon; retrieving candidate patterns from the recognized image pattern using a mask pattern; extracting a normal pattern from the retrieved candidate patterns using a check pattern; computing a relative distance and a relative angle of a mobile platform with respect to the beacon using size information of the extracted pattern; and recognizing the location of the mobile platform using the computed relative distance and relative angle. - View Dependent Claims (24, 25, 26)
