Abstract: An unmanned image capturing device and a method of operation thereof are provided. The unmanned image capturing device includes a movement device that moves the unmanned image capturing device; a camera; a communication circuit; a location detection circuit that detects a location of the unmanned image capturing device; a processor; and a memory that stores instructions. The processor moves the unmanned image capturing device, captures a plurality of images, detects a plurality of three-dimensional locations, at which the plurality of images are respectively captured, sends at least one of the captured images and information about the respective detected location of the at least one of the captured images, receives information about a change in the at least one of the captured images or information about an image selection, and controls the movement device to move the unmanned image capturing device to a location based on the received information.
