Abstract: An information processing device includes a microphone that acquires a speech signal, and at least one processor. In a case in which the processor determines a wake word is included in first recognition data derived from the speech signal, when the processor determines that control information, that is information related to a control processing, is included in second recognition data derived from the speech signal after the wake word, the processor executes a first control processing corresponding to the control information. When the processor determines that the control information is included in third recognition data derived from the speech signal acquired by the microphone during a first period after a predetermined condition related to an event that occurs after the wake word is satisfied or during execution of the first control processing, the processor executes a second control processing corresponding to the control information included in the third recognition data.

Abstract: While an information display device is initially placed at a standstill, a CPU stores acceleration responsive to gravitational force acquired by an acceleration sensor into a RAM. The CPU acquires acceleration in compliance with fixed timing acquired by the acceleration sensor and resulting from motion on the information display device. The CPU accumulates the acceleration acquired in compliance with the fixed timing within each prescribed period. Then, the CPU makes the accumulated acceleration agree with acceleration responsive to gravitational force stored in the RAM, thereby correcting a posture parameter. Based on the corrected posture parameter, the CPU determines whether a temporal image is to be displayed on a display unit.

Abstract: An imaging apparatus generates a 3D model using a photographed image of a subject and generates a 3D image based on the 3D model. When a corresponding point corresponding to a point forming the 3D model does not form a 3D model generated using a photographed image photographed at a different photographing position, the imaging apparatus determines that the point is noise, and removes the point determined as noise from the 3D model. The imaging apparatus generates a 3D image based on the 3D model from which the point determined as noise is removed.

Abstract: The matching processor acquires the key information such as position information and/or the like by the key information acquirer, and notifies to an external apparatus via the communicator. The matching processor stores the acquired key information in the storer corresponding to the identification information which is acquired from the external apparatus. When the acquired identification information does not exist in a AR data management table, the matching processor acquires the AR data by notifying the identification information to the external apparatus. When there is no empty record in a key information management table, key information of which usage date and time is old is considered as a deletion target. Moreover, when there is no empty record in the AR data management table, the AR data of which usage date and time is old is considered as the deletion target.

Abstract: The utility of a service using AR is improved. The information display apparatus which applies an information display according to augmented reality (AR) acquires a reference image for matching with a subject in a captured image and scale information which shows a scale of the subject in the reference image from an information provision apparatus. Then, an inputter-outputter of the information display apparatus displays the captured image as well as a distribution of the reference images by a scale of the subject. On this distribution display, a guide display according to the scale of the subject in the captured image is performed. This guide display moves on the distribution display corresponding to a change of an angle of view. Accordingly, it is easily set the angle of view by which the matching using the acquired reference image can be performed appropriately, and the convenience improves.

Abstract: A server sends to a client a message instructing movement of a display apparatus so that cameras comprising a view for creating a three-dimensional model can shoot a screen of a display apparatus. After movement is complete, the server causes an imaging parameter computation pattern image to be displayed on the screen of the display apparatus and instructs the client to cause the displayed pattern image to be shot by cameras. The server acquires images shot by the cameras from the client and seeks imaging parameters of the cameras on the basis of the pattern image included in the acquired images.

Abstract: A three-dimensional modeling unit creates a three-dimensional model from a pair of images stored in a keyframe storage in every several frame periods. A feature point detection unit detects feature points in images stored in the keyframe storage. Then, a positional change estimate unit estimates positional change of the detected feature points in a latest image and calculates conversion parameters for converting the created three-dimensional model to a three-dimensional model corresponding to the latest image based on the estimation results. Then, a reconstruction unit reconstructs the created three-dimensional model using the calculated conversion parameters and a image output unit outputs it to a display device on a frame period basis.
