1. A method for calibrating a lawnmower, the method comprising:
collecting, by a pair of Real Time Kinematic (RTK) antennas respectively set at a preset position and on the lawnmower, a preset number of position data of the lawnmower during moving of the lawnmower relative to a charging station;
performing straight line fitting using the preset number of the position data; and
determining, when the preset number of the position data fits a straight line, an orientation of the charging station based on a slope of the fitted straight line.
