1. A flying drone for shelf label checking, the flying drone comprising:
a flying mechanism configured to move along a flight path;
a camera mounted to the flying mechanism;
a camera interface connected to the camera and configured to transmit and receive data to and from the camera;
a flight control interface connected to the flying mechanism and configured to transmit and receive data to and from the flying mechanism; and
a processor configured to:
acquire a first image of a shelf having a plurality of shelf labels attached to a front surface thereof, the first image being acquired by the camera from a first distance from the front surface of the shelf,
extract shelf label regions in the first image,
set the flight path for the flying mechanism based on the extracted shelf label regions,
control the flying mechanism to fly the camera along the flight path to a second distance that is closer to the front surface of the shelf than the first distance,
acquire a second image with the camera of at least one shelf label from the second distance, and
check for a defect in the at least one shelf label based on information read from the at least one shelf label in the second image and management information for the at least one shelf label indicating an intended position and content for the at least one shelf label.
