Abstract: Provided are a flight control device, a flight control method, and the like for measuring the distance between the body of an aircraft and a target element during flight and controlling the distance in accordance with the measured value. This unmanned aircraft flight control device comprises: a distance sensor for measuring the distance between a target element and an unmanned aircraft that flies by control using an external input signal and/or pre-generated flight plan information, the distance sensor comprising an imaging camera that captures the target element, and a measured value determination circuit that determines a measured value of the distance using the captured image information; and a control signal generation circuit that generates a control signal for controlling the distance between the target element and the unmanned aircraft during flight, in accordance with the distance measurement value measured by the distance sensor.

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.
