Abstract: A method for large scene elastic semantic representation and self-supervised light field reconstruction is provided. The method includes acquiring a first depth map set corresponding to a target scene, in which the first depth map set includes a first depth map corresponding to at least one 5 angle of view; inputting the first depth map set into a target elastic semantic reconstruction model to obtain a second depth map set, in which the second depth map set includes a second depth map corresponding to the at least one angle of view; and fusing the second depth map corresponding to the at least one angle of view to obtain a target scene point cloud corresponding to the target scene.

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.
