Abstract: A server device performs machine learning on the relationship between the content of piloting of an aerial vehicle and the behavior of the aerial vehicle in response to the content of the piloting, and generates a learning model for automatically piloting the aerial vehicle. However, the aerial vehicle is piloted in various environments and conditions, and there are environments and conditions that are unsuited for achieving highly accurate and stable automatic piloting. Therefore, the server device performs the machine learning only in an environment or a condition suited for realizing the automatic piloting.

Abstract: A setting unit sets the operating mode of an aerial vehicle to a first operating mode that transmits, data generated by a host aerial vehicle and data received from another aerial vehicle to a processing device, or a second operating mode that transmits data generated by a host aerial vehicle to another aerial vehicle. At this time, setting unit sets the operating modes of each of a plurality of aerial vehicles using a setting method corresponding to the attributes of an airspace in which aerial vehicle flies, from among a plurality of setting methods that set the operating mode of aerial vehicle. The attributes of an airspace include attributes determined in accordance with a degree of importance pertaining to the process of transmitting data from aerial vehicle to a server device and/or attributes determined in accordance with the extent to which processes are distributed among a plurality of aerial vehicles.

Abstract: A specifying unit 51 of a flying body operation management device 50 specifies an airspace in which a propagation delay equal to or greater than a threshold value occurs in the uplink of a time-division duplex between a wireless communication terminal 30 and a wireless base station 41 to which wireless communication terminal 30 is wirelessly connected. Next, an assigning unit 52 of flying body operation management device 50 performs a process of assigning, with respect to each airspace, a flying body 10 having a wireless communication terminal 20. At this time, with respect to an airspace specified by specifying unit 51, assigning unit 52 limits the assigning of flying body 10 on which wireless communication terminal 20 is mounted.

Abstract: Baggage is connected to an aerial vehicle in a state in which the baggage is suspended by a connector such as rope. A learning unit of a server device performs machine learning on the relationship between the piloting of an aerial vehicle and the behavior of baggage on the basis of an aerial vehicle behavior history and a piloting history acquired by a first acquisition unit and a baggage behavior history acquired by a second acquisition unit. With this arrangement, the automatic piloting of the aerial vehicle at the time of lowering baggage is achieved.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: When utilizing a flying vehicle to monitor an animal that is grazing, the stress of the animal targeted for monitoring is mitigated. An acquisition unit acquires position information indicating the position of an animal that is grazing. A determination unit determines the reactivity of the animal to the approach of a flying vehicle. A setting unit sets a distance that depends on the determined reactivity. An instruction unit instructs the flying vehicle to start flying toward a monitoring position corresponding to the position indicated by the acquired position information and the set distance, and to perform processing for monitoring the animal on the basis of the monitoring position.

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.
