Abstract
A rotorcraft and an automatic landing system and method thereof are provided in the present disclosure. The automatic landing system of the rotorcraft includes a controller, a laser emitter, a camera, an electronic governor and a motor configured to drive a propeller of the rotorcraft to rotate. The laser emitter and the camera are both locate in a bottom portion of an airframe of the rotorcraft. The laser emitter has two emission heads, laser beams emitted from the two emission heads respectively are symmetrical about a central axis, the central axis is perpendicular to a horizontal plane of a ground, and an angle between each laser beam and the central axis is an acute angle. Simply with an operation of the laser emitter, the camera and the controller, the flight speed and displacement of the rotorcraft can be controlled to realize automatic landing in the present disclosure.
