Abstract: Time slot specifying unit reads out facility information of a facility to be inspected (specifically, a base station ID of a base station whose previous inspection day is included in a past predetermined period) from facility information storage unit. Daytime information acquiring unit acquires daytime information at positions at which base stations to be inspected are installed. Time slot specifying unit specifies non-backlight time slots based on the read-out facility information and the acquired daytime information. Operation plan generating unit generates an operation plan of drone in which facilities are shot in the specified non-backlight time slots. Operation plan outputting unit outputs the generated operation plan.

Abstract: Wind information storage unit acquires and stores wind information indicating the windspeed and wind direction of wind that blows at a plurality of spots neighboring a facility targeted for examination. Wind predicting unit predicts the windspeed and wind direction at the facility targeted for examination, based on the wind information acquired by wind information storage unit. Flight instructing unit instructs, with regard to drone that flies around the facility and acquires examination data of the facility, flight that avoids colliding with the facility due to wind of the windspeed and wind direction predicted by wind predicting unit, before arrival of the wind. Flight instructing unit gives an instruction for collision avoidance in the case where a change in the windspeed predicted by wind predicting unit is greater than or equal to a threshold value.

Abstract: Outward leg instructing unit provides a first instruction for causing drone to acquire examination data of a facility while flying in the vicinity of the facility. Position information acquiring unit acquires position information of a place of focus specified based on the examination data acquired in accordance with the first instruction. Return leg instructing unit provides, as a second instruction, an instruction for causing drone to acquire a greater amount of examination data than that acquired in accordance with the first instruction with regard to the place of focus indicated by the acquired position information, while flying so as to return on a path flown due to the first instruction. Return leg instructing unit provides as the second instruction an instruction to acquire examination data including image data of a greater number of shots, as compared with shooting performed in accordance with the first instruction.

Abstract: Related information acquiring unit acquires related information related to a facility to be inspected. Related information acquiring unit acquires shape information indicating the shape of a facility as related information. Required skill determining unit determines, when inspection data regarding the facility is acquired by causing drone to make a flight around the facility, a required skill needed to operate drone. Required skill determining unit determines the required skill regarding the facility based on the acquired related information regarding the facility. Required skill determining unit makes determination such that, the higher the level of complexity of a flight route along the shape of the facility that is represented by the acquired related information is, the higher the required skill is. Operation plan generating unit generates an operation plan for causing drone to make a flight while visiting facilities for which the level of the determined skill is the same.
