1. A method for calibrating a joystick, applicable to a remote control device, while the joystick is in a calibration mode, the method comprising:
obtaining an original parameter related to an original position of the joystick;
moving the joystick to a target point;
obtaining, by a processor, sampling parameters related to a sampled position of the joystick while the joystick is at the target point;
moving the joystick to a maximum angle;
obtaining, by the processor, a maximum angle value related to a position of the joystick while the joystick is at the maximum angle;
calculating, by the processor, a calibration parameter of the target point using the sampling parameters and the maximum angle value; and
calibrating the joystick according to the calibration parameter, wherein said calibrating the joystick includes
obtaining a new parameter of the joystick using the calibration parameter and the original parameter; and
converting the new parameter of the joystick into a joystick instruction configured for controlling a remotely controlled device.
