Patent ID: 11935182
Assignee: CANON KABUSHIKI KAISHA
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 0:
1. An information processing apparatus for generating a virtual view point image based on a plurality of captured images captured by a plurality of image capture apparatuses, comprising:
one or more memories storing instructions: and
one or more processors executing the instructions to:
estimate, based on the plurality of captured images, a three-dimensional shape of an object and generate corresponding three-dimensional shape data of the object;
obtain information indicating a depth of field of each of the plurality of image capture apparatuses;
perform first determination of determining a visibility determination region corresponding to each of the plurality of image capture apparatus in each of the plurality of captured images based on the information indicating a depth of field of each of the plurality of image capture apparatuses;
perform second determination of, in a case where an element among a plurality of elements forming the three-dimensional shape data of the object is included in the visibility determination region, determining whether or not the element is visible from an image capture apparatus, and in a case where an element among the plurality of elements forming the three-dimensional shape data of the object is not included in the visibility determination region, determining that the element is not visible from an image capture apparatus; and
generate a virtual viewpoint image, based on a determination result by the second determination, the obtained three-dimensional shape data and the plurality of captured images,
wherein, in generating the virtual viewpoint image, for each of the plurality of elements, texture corresponding to that element of the three-dimensional shape data is generated based on a captured image obtained from an image capture apparatus from which that element is determined to be visible by the second determination.
