The present invention is possible to control landing of an unmanned aerial vehicle by calculating a height and a direction of the unmanned aerial vehicle from the ground by using feature point extraction through size changes and image processing of an artificial sign photographed in a camera in accordance with distance changes by using the camera and the artificial sign. Accordingly, the present invention is possible to very simply stably obtain altitude information of high precision.
