  • Publication number: 20190187168
    Abstract: A wind direction and a wind speed are readily and accurately estimated at a desired position without using a wind direction and velocity sensor. Movement instruction means of a wind estimation system instructs an unmanned aerial vehicle (UAV), which includes a sensor unit that detects information about a position change, to move. Fall control means causes the UAV to free fall after the UAV is moved according to the instruction of the movement instruction means. Estimation means estimates at least one of a wind direction and a wind speed at a fall position based on the information about the position change detected by the sensor unit during a fall of the UAV.

  • Publication number: 20190019141
    Abstract: Association means of a logistics system associates authentication information on a user with the package and storing the associated authentication information into a storage means; Instruction means instructs an unmanned aerial vehicle into which the package is to be loaded to move to the location, based on location information on a location of a collection destination or a delivery destination of the package. Arrival determination means determines whether the unmanned aerial vehicle has arrived at the location. Checking means checks whether the user is at the location based on the authentication information associated with the package and on a situation of the location detected by the unmanned aerial vehicle or details of communication to and from a terminal of the user. Movement control means moves the unmanned aerial vehicle toward the user at the location when the checking means confirms that the user is at the location.

  • Publication number: 20190002104
    Abstract: To avoid interfering with a participant when information on a venue of a competition or an event is provided by using an unmanned aerial vehicle, participant position information acquisition means of an unmanned aerial vehicle escape system acquires participant position information on a position of the participant in the venue of the competition or the event. Movement instruction means instructs an unmanned aerial vehicle for providing information on the venue to move to a position defined based on the participant position information. Layout information acquisition means acquires layout information on a layout of the venue. Escape destination determination means determines an escape destination of the unmanned aerial vehicle based on the participant position information and the layout information. Escape means causes the unmanned aerial vehicle to escape to the escape destination determined by the escape destination determination means.
