Method for generating free viewpoint video image in three-dimensional movement and recording medium

摘要

The present invention provides a method for generating free viewpoint video image in three-dimensional movement capable of synthesizing the free viewpoint video image from a viewpoint which looks down on an object from above. This method includes a process of taking multi-viewpoint video images using a plurality of cameras located on an identical plane and a camera not located on the identical plane, a process of generating video image at a viewpoint having the same azimuth as a desired viewpoint and located on the plane from the multi-viewpoint video images of the cameras on the plane, and a process of generating video image at the desired viewpoint from video image of the camera not located on the plane and video image at the viewpoint having the same azimuth as the desired viewpoint and located on the plane.
