Title:
METHOD AND SYSTEM FOR SYNTHESIZING NOVEL VIEW IMAGE ON BASIS OF MULTIPLE 360 IMAGES FOR 6-DEGREES OF FREEDOM VIRTUAL REALITY
Document Type and Number:
WIPO Patent Application WO/2021/080096
Kind Code:
A1
Abstract:
The present invention relates to a method and a system for synthesizing a novel view image on the basis of multiple 360 images for 6-degrees of freedom (DoF) virtual reality, wherein multiple 360 images are used to construct a large-scale 6-DoF virtual environment and synthesize a scene at a new viewpoint. The method comprises the steps of: performing a 3D reconfiguration procedure on 360 images to reconstruct 3D geometric information and reconfigure a virtual data map integrating the multiple 360 images into one image; using a reference image closest to a viewpoint extracted from the virtual data map to apply a projection & vertex warping view synthesis algorithm so as to create view images corresponding to a user viewpoint; and mixing the view images for 6-DoF through a section formula relating to internal partition based on the distance between the position of the reference image and the position of the viewpoint.
