Abstract: Each time a command generation unit (250) acquires an image from an aircraft (30), a display unit (210) of an aircraft control apparatus (20) displays the image on a display (220). In this instance, upon determining a position of an inspection target within the image, the display unit (210) displays at least two markers indicating the inspection target. The two markers are arranged along the inspection target in such a way that the inspection target is positioned between the two markers. The marker is, for example, a solid line, but may be a dotted line or a dash-dotted line. Moreover, the marker is preferably of a predetermined color, for example, red.

Abstract: An aircraft control apparatus (20) includes a display unit (210), a display (220), an input unit (230), a selection unit (240), and a command generation unit (250). The command generation unit (250) acquires an image that has been generated by an image capture unit (350) of an aircraft (30). The display unit (210) displays, on the display (220), the image acquired by the command generation unit (250). The image includes at least one electric wire or at least one pipe that could be an inspection target. The input unit (230) displays, according to an input from a user, a line within the image displayed on the display (220). The selection unit (240) selects an inspection target by use of the line displayed by the input unit (230). The command generation unit (250) generates command information for the aircraft to photograph the inspection target while moving along the inspection target, and transmitting the command information to the aircraft (30).

Abstract: A route setting apparatus (10) includes a first acquisition unit (130) and a route setting unit (140). The first acquisition unit (130) acquires specification information that specifies a plurality of points. When setting the plurality of points, inspectors superimpose each of the plurality of points on an inspection target. The route setting unit (140) takes, as a flight route of an aircraft, a line connecting points acquired by moving the plurality of points indicated by the specification information in the same direction and for the same distance. For example, the route setting unit (140) sets a temporary flight route by connecting the plurality of points indicated by the specification information. Then, the route setting unit (140) sets a flight route by moving the temporary flight route.
