Information processing device and information processing method

Server apparatus, by controlling flight vehicle, causes flight vehicle to fly to a close range of a power-transmission line, and causes flight vehicle to capture images of the power-transmission line. Flight vehicle includes a positioning apparatus of GPS, and the flight of flight vehicle is controlled based on this measured position. On the other hand, each base station in communication network is provided with a positioning apparatus of GPS. The measured position of base station measured by the positioning apparatus is used to specify the error in position of flight vehicle determined by the positioning apparatus. Server apparatus restricts the flight of flight vehicle if the error in position of flight vehicle, which is determined by the positioning apparatus, that captures images of the power-transmission line is a threshold value or more.

Information processing apparatus and information processing method

Server apparatus, by controlling aerial vehicle, causes aerial vehicle to fly within a close range of an animal group, and causes aerial vehicle to capture images of the animal group. Aerial vehicle transmits captured image data to server apparatus via communication network, and server apparatus checks a health state of animals of the animal group using the captured image data with a method such as image analysis. Server apparatus performs machine learning using position information history of wireless terminals attached to animals (that is, a movement history of the animal group), specifies an area for checking the state of the animal group, and causes aerial vehicle to fly to the specified area and to capture images of the animal group.

An information processing apparatus includes a control unit that controls a first flying vehicle and a second flying vehicle. The first flying vehicle captures an image of a surface of a road. The second flying vehicle emits light onto the surface, such that a spot where a level difference is estimated, in advance, to occur on the surface, an image capturing direction in which the first flying vehicle captures an image of the spot, and a light emitting direction in which the second flying vehicle emits the light onto the spot have a relationship that causes, when the level difference exists, a shadow to occur at the spot and the shadow to be captured.

A flight information acquisition unit repeatedly acquires the respective flight status of a plurality of drones in flight. A flight irregularity determination unit determines whether or not the drones are flying in a manner deviated from a flight plan. When a flight status of a drone indicating flight deviated from the flight plan has been acquired, a first collision specification unit specifies the drone at risk of collision with a drone having that flight status. When a flight status indicating that there is a possibility of crash for a drone has been acquired, a flight status processing unit (such as a flight irregularity determination unit) sets a higher priority for processing based on the flight status acquired from that drone than for processing based on the flight status acquired from another drone.

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.
