Abstract: A management system includes a storage unit that stores schedule information that indicates schedules of a plurality of tasks to be performed by the same flight vehicle. The schedule information includes types of the plurality of tasks, date/times of the plurality of tasks, and locations at which the plurality of tasks are to be performed. When the types, the date/times, and the locations that are included in the schedule information stored in the storage unit satisfy an integration condition, an integration unit integrates the schedules of the plurality of tasks. An output unit outputs integrated schedule information indicating the schedules of the integrated tasks.

Abstract: 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.

Abstract: Recovery of a flying vehicle that has fallen to the ground is facilitated. A positioning unit measures a position of the flying vehicle during flight. A specification unit specifies a feature of a region on the ground corresponding to the measured position. A determination unit determines a sending interval of position information indicating the position of the flying vehicle, according to the specified feature. A sending unit sends the position information at the determined sending interval.

Abstract: Setting unit performs the setting of each of the operating modes of a plurality of aerial vehicles on the basis of communication quality information of the planned route of the plurality of aerial vehicles that fly in a group. Specifically, setting unit firstly specifies the planned positions and periods in which each aerial vehicle is to fly from the flight plan information of the plurality of aerial vehicles that fly in a group. Next, setting unit specifies a communication quality of first wireless communication unit of each aerial vehicle in each position and each period from the communication quality information that represents the communication quality in the specified positions and periods. Then, setting unit specifies an operating mode setting schedule of main unit mode and auxiliary unit mode, which sets an aerial vehicle having a specified communication quality, and sets the remaining aerial vehicles as auxiliary units.

Abstract: A flight control apparatus that enables a flying object to safely pass another flying object includes a detection unit configured to detect, in a predetermined range from a flying object, another flying object. A specifying unit is configured to specify a moving direction of the detected other flying object. A judging unit is configured to judge, based on the specified moving direction, whether or not passing is possible. A determination unit is configured to determine, based on a relationship between the flying object and the other flying object, content of a passing operation to be performed with respect to the other flying object. A flight control unit is configured to, if it is judged that passing is possible, control flight of the flying object and perform the passing operation according to the determined content.

Abstract: Flight type determination unit determines a flight type of drone on the basis of parameters obtained by flight schedule obtainment unit. The flight type includes a travel type, which uses a destination as a parameter, a touring type, which uses a range in space (a touring range) as a parameter, and a hovering type, which uses a position in space (a hovering position) as a parameter. Allocation rule storage unit stores allocation rules for flight airspace corresponding to each of the plurality of flight types. Flight airspace allocation unit allocates flight airspace to drone on the basis of allocation rules corresponding to the flight type of that drone as indicated by the parameters obtained for that drone.

Abstract: An information apparatus includes a schedule obtainment unit that obtains flight schedule information transmitted from terminals. Allocation unit allocates an airspace and a permitted flight period to drone based on the obtained flight schedule information. If there is a predetermined commonality in the airspaces and the flight directions of multiple drones, allocation unit causes those multiple drones to share the airspace under the condition that formation flight in which distances therebetween are controlled is performed. Allocation unit determines an arrangement in which multiple drones are aligned in the order in which drones withdraw from formation flight as the arrangement of multiple drones during formation flight. Also, allocation unit determines an arrangement in which drone that does not include a formation flight function is in front and drone that includes formation flight function follows therebehind.

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: 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.
