1. A moving object capable of recognizing an image comprising:

  • a camera for capturing an image of a docking direction pattern capable of directing a moving object to a docking location;

    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 of the extracted docking direction pattern to the number of pixels of the docking direction pattern captured at a reference location;

    an offset-information calculator for calculating a central point of the extracted docking direction pattern, a central point contained in the captured image, and the distance information of the distance to the docking location, and calculating moving-object offset information from the docking location; and

    a wheel drive for driving wheel operations of the moving object according to the offset information and the distance information.
