Abstract: A high-precision positioning result in self-positioning is provided. An information processing apparatus acquires a first coordinate position inside an image of each light source included in an image captured with an imaging device among multiple light sources whose coordinate positions are known in a three-dimensional space to derive at least a coordinate position or an orientation of an own device in the three-dimensional space based on a coordinate position of the light source included in the image in the three-dimensional space and the first coordinate position. The apparatus estimates a height of the imaging device in the three-dimensional space to perform positioning processing using information on the estimated height of the imaging device, acquires a second coordinate position of the light source on the image corresponding to the positioning processing result, and corrects the height of the imaging device based on the first coordinate position and the second coordinate position.

Abstract: An information transmission system includes a transmission apparatus and a reception apparatus and uses visible lights as transmission media. The transmission apparatus includes a generating unit and a first replace unit. The generating unit generates a multi-value symbol stream. The first replace unit replaces the multi-value symbol stream generated by the generating unit to a discontinuous symbol stream. The discontinuous symbol stream is a symbol stream without a sequence of identical symbol values. The number of identical symbol values in the sequence is equal to or greater than a predetermined number. The reception apparatus includes an acquiring unit and a second replace unit. The acquiring unit acquires the discontinuous symbol stream. The second replace unit replaces the discontinuous symbol stream acquired by the acquiring unit to the multi-value symbol stream according to a predetermined rule.

Abstract: Moving-objects movable in a workspace, each includes an imaging unit with a two-dimensional light receiving surface; and a decoding processing unit. If light received by an imaging surface of the imaging unit is brightness-modulated information, the decoding processing unit decodes the received light to the information. If the information decoded by the decoding processing unit contains spatial position information of moving-objects other than a self-moving-object, the self-moving-object receives the light from light sources, has the decoding processing unit decode the light to acquire pieces of position information of the other moving-objects, thereby acquiring position information of the self-moving-object in the workspace from these pieces of position information.

Abstract: A light receiver of a communication apparatus receives light from an LED that emits light based on a light-emission pattern defined by an ID. An ID acquirer specifies the light-emission pattern from light received by the light receiver and acquires the ID. A transceiver transmits the acquired ID to a service server that stores an ID/URL table associating together the ID and a URL of information relating to equipment equipped with the LED, and receives a corresponding URL. An information acquirer acquires the information relating to the equipment based on the URL received by the transceiver.
