    a range landmark extracting unit which, if a new distance is sensed, updates the candidate range landmark information and extracts actual range landmark information from the candidate range landmark information; and

    a position recognizing unit which recognizes a position of the position recognizing apparatus based on the extracted actual range landmark information.
