  • Publication number: 20220254262
    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.

  • Publication number: 20220242559
    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.

  • Publication number: 20220238026
    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.

    Abstract: A flight control apparatus includes an acquisition unit that acquires a flight plan in which first flight conditions are described, and information that indicates a time limit set with respect to a position on a path along which an air vehicle is to fly. An arrival judging unit judges, based on the acquired information, whether or not the air vehicle has arrived at the position within the time limit. A condition determination unit determines a second flight condition if it is judged that the air vehicle has not arrived at the position within the time limit. A flight control unit controls flight of the air vehicle selectively adopts a first flight control method which follows the first flight conditions or a second flight control method which follows the second flight condition based on a result obtained by the arrival judging unit.

  • Patent number: 11380209
    Abstract: Allocation result accumulation unit accumulates allocation results of each business operator that requests allocation of flight airspace of drone. Allocation result accumulation unit accumulates, as the allocation results, an allocated airspace amount represented by the size of allocated flight airspace and the period in which flight in the flight airspace is permitted. When allocation requests are received from multiple business operators, flight airspace allocation unit allocates flight airspace by giving priority to a high priority business operator according to the allocation results accumulated in allocation result accumulation unit with respect to each business operator. Flight airspace allocation unit allocates the flight airspace by assigning a higher priority to a business operator for which the allocated airspace amount that has been accumulated is small.

  • Publication number: 20210350717
    Abstract: 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.

  • Publication number: 20210250971
    Abstract: If a propagation delay equal to or greater than a threshold value has been detected in the uplink of the time-division duplex between a first wireless communication terminal and a first wireless base station, a suppression unit 52 controls communications of the first wireless communication terminal. In accordance with the propagation delay between a wireless communication terminal DR1 and a wireless base station BS1, wireless communication terminal DR1 transmits UL data ahead of time by the length of said propagation delay. This may cause communication errors to occur in wireless communication terminals DR2 and MT1 that are wirelessly connected to a wireless base station BS2, which is different from wireless base station BS1 to which wireless communication DR1 is wirelessly connected. Accordingly, suppression unit 52 suppresses said communication errors by controlling communications by wireless communication terminal DR1.
