Patent Images
1. A device that controls a flight altitude of an unmanned aerial vehicle having mounted thereon an imaging device that captures an image of a ground, the device comprising:
- one or more memories; and
circuitry which, in operation,recognizes, as a plurality of markers, a plurality of relatively movable objects located on the ground from the image captured by the imaging device, each of the plurality of markers attached to one of the plurality of relatively movable objects,calculates, by a processor, an area of a polygon formed by the plurality of markers, andcontrols the flight altitude of the unmanned aerial vehicle in such a way that the area of the polygon is maximized.
