The present invention suppresses the case where communication performed by a radio communication apparatus of one flight vehicle is negatively influenced in the case where the radio communication apparatus of the one flight vehicle is connected to a radio base station that is experiencing interference due to a radio communication apparatus of another flight vehicle. A distance specification unit specifies, for each airspace, a distance between a first flight vehicle and a second flight vehicle that has a radio communication apparatus and is located in a cell formed by a radio base station that is experiencing interference due to a radio communication apparatus of the first flight vehicle. An instruction unit instructs, in each airspace, the first flight vehicle and the second flight vehicle to maintain the distance specified for the airspace by the distance specification unit when flying.

The present invention aims to control position of flying object with respect to a structural object in a situation where it is difficult to perform positioning based on radio signals transmitted from a satellite. A position identification unit identifies position of flying object in troublesome GPS signal reception space, using different methods for coordinate axes. Specifically, position identification unit identifies position, on Z axis (first coordinate axis), of flying object in troublesome GPS signal reception space, based on distance from flying object to structural object (distance measured at time of position identification), and identifies positions, on X and Y axes (second coordinate axes), of flying object based on change in shape of structural object in respective axis directions of X and Y axes (second coordinate axes) (history of distance from flying object to bridge B measured multiple times until position identification).

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.

Assignment unit assigns flight vehicles having radio communication apparatuses to airspaces. At this time, assignment unit limits the assignment of flight vehicle to a specified airspace in which a parameter specified by specification unit is in a predetermined range (e.g., an airspace in which the path loss of the physical downlink channel to radio communication apparatus is less than or equal to a threshold value).

The accuracy of an index indicating growth conditions of a crop obtained from a shot image is improved, while reducing the flight time of an aircraft shooting the crop. Crop image acquisition unit acquires an image of a crop region shot by drone. Index calculation unit calculates an index indicating growth conditions of a crop shot in the image based on the acquired image of the crop region. Flight instruction unit instructs, if a portion (low index region) regarding which the calculated index is less than a predetermined index threshold is present in the crop region, drone to shoot the low index region while increasing the resolution of the image. Specifically, flight instruction unit makes an instruction to shoot the portion while performing a low-altitude flight at an altitude lower than that when the image regarding which the index of the low index region has been calculated has been shot.

Information processing apparatus

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.

Flight cessation detection unit detects that drone has ceased flying at an unexpected site. Situation information acquisition unit acquires, as situation information indicating a situation related to retrieval of the drone, information on weather in an area in which the drone has flown. Retrieval procedure determination unit determines a retrieval procedure for the drone based on a situation indicated by the acquired situation information. Retrieval procedure determination unit, upon detecting a time period having specific weather based on the acquired information on weather, determines a retrieval procedure in which the time period is designated as a retrieval time.

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.

The location detection unit detects a destination location for delivery of an item by a drone. The release determination unit determines whether the drone transporting the item can release and place the item at the destination. Upon determination that the release and placement is not possible, a standby airspace determination unit determines a standby airspace within which the drone waits. The wait-time determination unit determines a wait-time for the drone in the determined standby airspace. The wait-time determination unit determines a wait-time by which the drone can arrive at a next destination by a scheduled arrival time following departure of the drone departs after standby. The standby instruction unit issues to the drone an instruction related to the standby.

If a propagation delay equal to or greater than a threshold value is detected in the uplink of a time-division duplex between a first wireless communication terminal and a first wireless base station, a suppression unitperforms control pertaining to resources in the time-division duplex of a first wireless communication terminal. Thereby, communication errors that occur in a second wireless communication terminal wirelessly connected to the second wireless base station that is different from the first wireless base station, to which the first wireless communication terminal is wirelessly connected, is suppressed by uplink communication performed by the first wireless communication terminal in accordance with the propagation delay. For example, this suppression process is a process pertaining to the assignment of resources a time-division duplex with respect to the first wireless communication terminal.

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.
