Title:
FREE-VIEWPOINT IMAGE GENERATION METHOD AND FREE-VIEWPOINT IMAGE GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/147329
Kind Code:
A1
Abstract:
A free-viewpoint image generation method comprises an acquiring step (S201) of acquiring a multi-viewpoint image including N (N is an integer of 2 or more) images with N viewpoints, and a generating step (S202) of generating from the acquired multi-viewpoint image a free-viewpoint image which is an image of a virtual viewpoint different from the N viewpoints. The generating step (S202) includes: identifying, using a three-dimensional model generated from the N images, N reference regions in the N images which correspond to a region to be processed in the free-viewpoint image; estimating, from N pixel components in the N reference regions of the N images, pixel components of the region to be processed in the free-viewpoint image at a predetermined resolution higher than a resolution of each of the N reference regions; and generating an image composed of the estimated pixel components as the free-viewpoint image.
