Title:
CAMERAWORK GENERATING METHOD AND VIDEO PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/030206
Kind Code:
A1
Abstract:
This camerawork generating method includes: a model generating step (S112) of generating a three-dimensional model (152) of a scene, from a multi-viewpoint video (151) in which images of the same scene are captured from different viewpoints; a target scene determining step (S113) of determining, from within the abovementioned scene, a target scene (153) of which a free viewpoint video (156), in which the three-dimensional model (152) is viewed from a virtual camera, is to be generated; and a camerawork generating step (S114) of generating camerawork (154) representing variations over time in the position and attitude of the virtual camera in the free viewpoint video (156).
