Abstract: A method and a device for gigapixel-level light field intelligent reconstruction of a large-scale scene are provided. The method includes: obtaining a coarse three-dimensional geometric model based on a multi-view three-dimensional reconstruction system; constructing an implicit representation of the meta-deformed manifold on the coarse three-dimensional geometric model; and optimizing the implicit representation of the meta-deformed manifold to obtain the light field reconstruction in the form of free viewpoint rendering of the large-scale scene.
