Abstract: A method and a system for synthesizing a novel-view image based on multiple 360 images for 6DOF virtual reality, in which a large-scale 6-DOF virtual environment is implemented, and a scene is synthesized at a novel viewpoint, are provided. The method includes performing a 3D reconfiguration procedure for the 360 images to recover 3D geometric information, and to reconfigure a virtual data map in which the multiple 360 images are integrated into one image, producing a view image corresponding to a viewpoint of a user by applying a view synthesis algorithm of projection & vertex warping process using a reference image which is closest to a viewpoint extracted from the virtual data map, and blending view images for 6DoF through a section formula for inner split based on a distance between a position of the reference image and a position of the viewpoint.
