摘要： 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.

摘要： 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.

摘要： The distance between two points specified on an object is measured. The imaging part acquires a pair of images having parallax in one imaging operation on one and the same object. The display part displays a display image based on at least one image of the pair of images acquired. The reception part receives a start point and an end point specified on the object in the display image. The distance acquisition part calculates the positions in a real space of the start and end points specified on the object based on one pair or multiple pairs of images and acquires the distance between the start and end points on the object based on the calculated start and end point positions in the real space.

摘要： 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.

摘要： A generating unit generates a 3D model of an object based on pair images obtained for the same object. An extracting unit extracts plural first feature points from a to-be-synthesis 3D model and plural second feature points from a synthesis 3D model. An obtaining unit obtains a coordinate conversion parameter based on the plural first feature points and second feature points. A converting unit converts a coordinate of the synthesis 3D model in a coordinate in the coordinate system of the to-be-synthesis 3D model using the coordinate conversion parameter. A synthesizing unit synthesizes all converted synthesis 3D models with the to-be-synthesis 3D model, and unifies feature points. A storing unit stores the synthesized 3D model of the object and information on the unified feature points in a memory card, etc. The stored data is used in an AR process.

摘要： An aging-resistant rubber material with an improved heat resistance without deteriorating the moldability even if a rubber layer is formed from an aqueous latex of rubber and without any cost increase, even if a surface tack prevention treatment by an antitack agent is carried out, can be produced by applying a coating liquid containing an amine-based antioxidant in solution or dispersion to the surface of a cross-linked rubber material, followed by heating to a temperature of 80° C. or higher, thereby diffusing the amine-based antioxidant into the rubber material. When a coating solution containing an antitack agent together with the amine-based antioxidant in solution or dispersion is used, the surface tack prevention treatment of the cross-linked material as a product can be made at the same time.

摘要： In three-dimensional modeling apparatus, an image obtaining section obtains image sets picked up by stereoscopic camera. A generating section generates three-dimensional models. A three-dimensional model selecting section selects a first three-dimensional model and a second three-dimensional model to be superimposed on the first three-dimensional model among generated three-dimensional models. A extracting section extracts first and second feature points from the selected first and second three-dimensional model. A feature-point selecting section selects feature points having a closer distance to stereoscopic camera from the extracted first and second feature points. A parameter obtaining section obtains a transformation parameter for transforming a coordinate of the second three-dimensional model into a coordinate system of the first three-dimensional model. A transforming section transforms the coordinate of the second three-dimensional model into the coordinate system of the first three-dimensional model. And a superimposing section superimposes the second three-dimensional model on the first three-dimensional model.

摘要： 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.

摘要： A control part 210 sets up an exposure condition under which the bright part of the object is properly exposed and an exposure condition under which the dark part of the object is properly exposed. The control part 210 controls the first and second imaging part 110 and 120 to capture images with the set exposures, whereby a pair of images captured with different exposures is obtained. The control part 210 extracts corresponding points that are characteristic points corresponding between the image pairs. The control part 210 optimizes the extracted corresponding points based on the density of corresponding points between the images constituting an image pair captured with the same exposure and based on the pixel value of the corresponding points between the images captured with different exposures. The control part 210 creates 3D modeling data using the optimized corresponding points.
