Abstract:
A transmission-side information terminal displays a marker whose wavelength changes with time on the basis of a tag ID acquired from a management server. A receiving-side information terminal takes an image to acquire the tag ID, and transmits storage instruction information to a distribution server, the storage instruction information including the tag ID, an area number indicating a position of the receiving-side information terminal and image data acquired by taking an image. The image distribution server stores the tag ID, the area number and the image data in the storage instruction information in association with one another. The transmission-side information terminal transmits query information including the tag ID acquired from the management server and the area number indicating its own position to the image distribution server, thereby acquiring image data associated with the tag ID and the area number from the image distribution server.
Abstract:
An advertisement display device displays an outdoor advertising image and emits light (advertisement ID light) modulated in accordance with the advertisement ID and having the luminance changed temporally in the same direction as the display direction of the outdoor advertising image. Receiving the advertisement ID light, a portable terminal demodulates and decodes it to acquire the advertisement ID and sends advertisement recognition information including the advertisement ID, time, location of the portable terminal, direction from the portable terminal to the advertisement display device, and terminal ID to a server. The server aggregates the advertisement recognition information for each advertisement and for each time window and creates advertising effect information.
Abstract:
An information processing apparatus performs positioning processing to acquire coordinate positions inside images of light sources included in an image captured with an imaging device among multiple light sources (position indicators) whose coordinate positions in a three-dimensional space are known to derive at least either of a coordinate position and an orientation of an own device (moving body) in the three-dimensional space based on coordinate positions of the light sources in the three-dimensional space included in the image and the coordinate positions inside the images of the light sources. The information processing apparatus uses information on light sources in which an angle of a light source from the imaging device to a predetermined direction or a prospective angle between light sources in a horizontal direction satisfies a predetermined condition to derive at least either of the coordinate position and the orientation of the own device.
Abstract:
A position obtaining device includes a processor. The processor, in response to a condition being met, derives a first attitude angle as an attitude angle of the device based on first light sources and positions thereof on an image obtained by a first camera; in response to the attitude angle of the device being known, derives a three-dimensional position of the device based on two or more second light sources and positions thereof on an image obtained by a second camera, and in response to a predetermined number of second light sources or more being captured in the image, derives the three-dimensional position and a second attitude angle as the attitude angle of the device; and integrates a result of the first attitude angle and a result of the three-dimensional position and the second attitude angle to estimate the attitude angle and the three-dimensional position of the device.
Abstract:
A position obtaining device includes a driver and a processor. The processor, in response to a velocity of the device being moved by the driver being a predetermined velocity or less, derives a first attitude angle with a first likelihood as an attitude angle of the device; in response to a predetermined number of second light sources or more being captured in an image obtained by a second camera, derives a three-dimensional position of the device and a second attitude angle with a second likelihood lower than the first likelihood as the attitude angle of the device; determines a likelihood of the attitude angle and the three-dimensional position of the device estimated based on a result of the first attitude angle and a result of the three-dimensional position and the second attitude angle; and controls the velocity in accordance with the determined likelihood.
Abstract:
An information management apparatus includes at least one processor configured to execute a program stored in a storage. The at least one processor acquires sequentially captured frames. The at least one processor acquires a movement state of a position of a light source in an imaging area, based on light source images contained in the acquired frames. The light source transmits information by means of light including an illumination pattern of the light. The at least one processor causes the storage to store the information and the movement state in association with each other.
Abstract:
An optical communication apparatus includes a light receiving unit, a wavelength band determining unit and an estimating unit. The light receiving unit receives light which changes to predetermined wavelength bands in a predetermined cycle according to communication object information, for a predetermined light reception period. The wavelength band determining unit determines each wavelength band of the light received by the light receiving unit. The estimating unit estimates that a wavelength band of the light received by the light receiving unit is any one of the predetermined wavelength bands, in a case where said wavelength band determined by the wavelength band determining unit is not any one of the predetermined wavelength bands.
Abstract:
A portable terminal sends to a second server sound contents request information comprising a tag ID corresponding to light received from an illumination device, the light-receiving position on the light-receiving surface, and the area ratio of the light-receiving range to the light-receiving surface in order to acquire sound contents. The second server 700 combines individual sound contents corresponding to the tag ID in the sound contents request information, first basic sound contents corresponding to the light-receiving position, and second basic sound contents corresponding to the area ratio. Then, the second server creates sound contents for giving information about the object present at the location where the illumination device emitting the light corresponding to the tag ID is installed and the direction and distance of the object when seen from the portable terminal and sends the sound contents to the portable terminal.
Abstract:
Provided is an information processing system that includes a server and a client device. The server stores identification information and associated content in memory, and transmits the identification information, using light that varies over time as a communication medium. The client device continuously senses and decodes the light varying in time into the identification information, transmits the decoded identification information to the server, receives content transmitted from the server in response to the transmission of identification information, and displays received content. A controller included in the client device detects an operation on the displayed content from an input device, and applies control to transmit process details according to the detection to the server. The server additionally executes the process details transmitted from the client device, and updates the content to content that includes the execution results.
