  • Publication number: 20210174080
    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.

  • Publication number: 20210155342
    Abstract: Piloting assistance from a remote location is provided to a pilot of a flight vehicle. A server selects captured images. The captured images include flight vehicle viewpoint images that were captured by an image capturing function of the flight vehicle, or pilot viewpoint images that were captured by an image capturing apparatus and show the flight of the flight vehicle. The server provides selected captured images to an assister terminal with priority. The server determines the display with priority based on information related to the flight of the flight vehicle. For example, the server determines the captured images that are to be displayed with priority based on a state during the flight of the flight vehicle. States include, for example, the altitude, speed, orientation, battery amount, and motor rotation speeds of the flight vehicle, as well as the distance between the flight vehicle and a work object.
