An information processing apparatus is provided. A three-dimensional model of an object, which has been obtained by capturing an image of the object in an imaging area from a plurality of positions, and information indicating a position of the object with respect to the imaging area are obtained. A virtual viewpoint image that includes the object is generated based on the three-dimensional model of the object through performing correction that accords with a position of the object, on the object in the virtual viewpoint image.

Information processing apparatus, information processing method, and medium

An information processing apparatus obtains object information representing a position and a shape of an object in an image capturing region of which image is captured from different directions by a plurality of image capturing apparatuses, discriminates between a visible region that can be seen from a specific position in the image capturing region and an occluded region that cannot be seen from the specific position due to occlusion by the object based on the object information, and generates a virtual viewpoint image that displays information based on a result of the discrimination, the virtual viewpoint image being based on image data based on image capturing by the plurality of image capturing apparatuses and virtual viewpoint information indicating a position and a direction of a virtual viewpoint.

Information processing apparatus, information processing method, and non-transitory computer-readable storage medium

The technique of this disclosure suppresses a reduction in visibility of a predetermined object in virtual viewpoint image data. An image processing apparatus includes: an image capturing information acquisition unit configured to acquire image capturing information indicating a position and orientation of each of a plurality of image capturing apparatuses; an object information acquisition unit configured to acquire object information indicating a position and orientation of an object to be captured by the image capturing apparatuses, the object having a specific viewing angle; and a determination unit configured to determine, based on the acquired image capturing information and the position and orientation of the object indicated by the acquired object information, an image to be used for generating a virtual viewpoint image according to a position and orientation of a virtual viewpoint among a plurality of images based on capturing by the image capturing apparatuses.

Image processing apparatus, image processing method, and storage medium

a processing system comprises a plurality of image capturing units configured to capture a space including an object and configured to be used for generating a virtual viewpoint image representing a view from a virtual viewpoint; and a presenting unit configured to perform presentation for determining an orientation of the object in the space.

Processing system, processing method and non-transitory computer-readable storage medium
