Unmanned aerial vehicle landing control device and control method

The invention discloses an unmanned aerial vehicle landing control device which comprises a controller, a buffering and damping device, a millimeter wave radar and a binocular vision camera. The millimeter-wave radar, the binocular vision camera and the buffering and damping device are respectively connected with the controller; the control method of the unmanned aerial vehicle landing control device is characterized by specifically comprising the following steps that S1, when the unmanned aerial vehicle returns and is 10 meters away from a landing point, the millimeter wave radar and the binocular vision camera are used for recognizing the road condition of the landing point, and the distance difference between the highest position and the lowest position of a landing area is measured; s2, after the unmanned aerial vehicle flies to the position above the landing area, the controller adjusts the buffering and damping device to be adjusted downwards according to the distance difference between the highest posi
