Moving object capable of recognizing image and moving-object directing system equipped with the same
First Claim
1. A system for directing a moving object, comprising:
- a charging device on which a docking direction pattern is printed, such that a central point of the docking direction pattern for directing the moving object to a docking location and a power-supply terminal are arranged in a straight line; and
the moving object,the moving object including;
a camera for capturing an image of the docking direction pattern;
a docking direction pattern extractor for extracting the docking direction pattern and its central point from the captured image;
a distance-information calculator for calculating distance information from a current location to the docking location according to a ratio of the number of pixels ranging from the central point of the docking direction pattern to the edge of the docking direction pattern of the captured image to the number of pixels from the central point to the edge of the docking direction pattern captured at a reference location;
an offset-information calculator for calculating the angle between the current location and the docking location; and
a wheel drive for driving wheel operations of the moving object according to the offset information and the distance information.

Abstract
A moving object capable of recognizing an image and a system for directing the moving object are disclosed. The system for directing the moving object includes: a charging device on which a docking direction pattern is printed, such that a central point of the docking direction pattern for directing the moving object to a docking location and a power-supply terminal are arranged in a straight line; and a moving object for driving wheel operations to allow the central point of the docking direction pattern captured by a camera to be identical with a central point of an image captured by the camera, and moving to the docking location. The moving-object directing system drives a wheel to track a central point of the docking direction pattern captured by a camera, such that it can quickly and correctly move to the docking location of the charging device.
