Abstract: Provided is an unmanned aircraft that is used to quickly and accurately specify a target location and operate a specific mechanism having a predetermined function at the target location. An unmanned aircraft 100 refers to a target location marker pattern 120d3 representing an appearance of a target location marker 161 disposed to have a predetermined relative position relationship with the target location, detects an image portion corresponding to the target location marker 161 from an image obtained by a camera 106 that obtains the image below the unmanned aircraft 100, and is guided directly above the target location, based on the image portion, where the specific mechanism is operated.
