To reduce environmental influence in flight (including taking-off and landing) of a flying object, main drone current position information acquisition unit acquires a current position of a main drone from a main drone control terminal, and provides the current position to the movement instruction unit. The sub-drone current position information acquisition unit acquires a current position from the sub-drone, and provides it to the movement instruction unit. The movement instruction unit determines a movement position of the sub-drone on the basis of the current position of the main drone. In addition, the movement instruction unit generates a movement instruction for the sub-drone based on a difference between the current position and the movement position of the sub-drone, and transmits the movement instruction to the sub-drone. The drive control unit acquires the movement instruction transmitted from the sub-drone control terminal.

Information processing system, information processing method, and program

A specific object is quickly detected to improve safety of flight. A control unit of an unmanned aerial vehicle control system obtains an image in which surroundings of an unmanned aerial vehicle are captured, the unmanned aerial vehicle being movable in any direction. A control unit for obtaining movement direction information about a movement direction of the unmanned aerial vehicle. A control unit for specifying a part to be processed in the image based on the movement direction information. A control unit for performing detection processing on the part to be processed to detect a specific object. A flight control unit for controlling flight of the unmanned aerial vehicle based on a result of the detection processing.

A flight route information acquisition module acquires flight route information indicating a flight route of an unmanned aerial vehicle in a real space. A real space position/direction identifier identifies a visually recognized position and a visually recognized direction in the real space. A flight route image generator generates a flight route image representing the flight route viewed from the visually recognized position in the visually recognized direction based on the flight route information. A display controller displays the flight route image under a state in which a position of the flight route image is matched with a situation viewed from the visually recognized position in the visually recognized direction in the real space on a display.

Flight route guidance system, flight route guidance device and flight route guidance method

Provided are a display control system, a display control device, and a display control method, which are capable of appropriately controlling a display state of an image photographed by a camera included in an unmanned aerial vehicle. A sensing data acquisition module acquires an aerial vehicle photographing image photographed by the camera included in the unmanned aerial vehicle in flight. A determiner determines whether an operator of the unmanned aerial vehicle is able to visually recognize the unmanned aerial vehicle based on sensing data on at least one of the unmanned aerial vehicle or the operator. A display controller controls a display state of the aerial vehicle photographing image on a display depending on a result of determination by the determiner.

A transport system identifies an attribute of a ground on the basis of sensing data obtained by sensing the ground in a transport destination area, which is performed in flight by an Unmanned Aerial Vehicle transporting an article, and determines a region in the ground as an arrangement place of the article on the basis of the identified attribute.

Determining method of arrangement place, transport system, and information processing device

A sensor unit () included in a display device () detects a shift in orientation of a display () included in the display device () in a real space. A display control device configured by a control unit () changes the sight line direction in a virtual space, which includes a plurality of still and moving objects, in accordance with the detected shift in orientation, and generates an image representing a view of the virtual space in the sight line direction. The generated image is displayed on the display (). The display control device configured by the control unit () then specifies a focus object among the objects, transfers an observation site about the focus object in the direction opposite to the direction of change in the sight line direction, and then generates the image of the virtual space from the observation site in the sight line direction.

Display controlling device, display controlling method, program, and non-transitory computer-readable information recording medium

A device searches a file being recorded that includes lines sorted in accordance with keys included in the lines to find a line that matches a pattern. When the device receives a pattern, it initializes upper and lower limits of a search range and calculates a middle position between the limits. It acquires, from the file, a middle line that starts at or before the middle position and ends after it. If the key included in the middle line matches the pattern, it outputs the middle line and re-sets the upper or lower limit based on whether the key included in the middle line is greater or less than the pattern and, if there is a distance greater than a length of a newline between the limits, repeats the procedure starting from the middle position. Otherwise, it outputs a result to the effect that no matching line has been found.

Provided are a display control system, a display control device, and a display control method, which are capable of appropriately controlling a display state of an image photographed by a camera included in an unmanned aerial vehicle. A sensing data acquisition module acquires an aerial vehicle photographing image photographed by the camera included in the unmanned aerial vehicle in flight. A determiner determines whether an operator of the unmanned aerial vehicle is viewing the unmanned aerial vehicle with his or her eyes based on sensing data on at least one of the unmanned aerial vehicle or the operator. A display controller controls a display state of the aerial vehicle photographing image on a display depending on whether determination that the operator is not viewing the unmanned aerial vehicle with his or her eyes is continued.

A state information storage () stores an observation position, an observation direction, and a base direction in a virtual space. Upon acceptance of an instruction input given to an external controller and indicating a moving direction, an observation position updater () updates the observation position so that the observation position moves in the moving direction indicated by the instruction input relative to the base direction. An observation direction updater () updates the observation direction in accordance with a change in orientation of a display apparatus () as detected by a detector (). An obtainer () obtains a relative position between the controller and the display apparatus (). A base direction updater () updates the base direction on the basis of the observation direction and of the obtained relative position.

An alerting apparatus () includes an obtainer (), a detector (), and an outputter (). The obtainer () obtains a group of images of a group of objects imaged by a stereo camera, the group of objects including a plurality of external objects. The detector () detects objects approaching each other in accordance with positions and parallaxes of the plurality of imaged objects based on the obtained group of images. The outputter () outputs an alert reflecting a degree of approach, the degree representing a degree of closeness between the detected objects.
