Delicate Textured Mesh Recovery from NeRF via Adaptive Surface Refinement
Abstract
Neural Radiance Fields (NeRF) have constituted a remarkable breakthrough in image-based 3D reconstruction.
However, their implicit volumetric representations differ significantly from the widely-adopted polygonal meshes and lack support from common 3D software and hardware, making their rendering and manipulation inefficient.
To overcome this limitation, we present a novel framework that generates textured surface meshes from images.
Our approach begins by efficiently initializing the geometry and view-dependency decomposed appearance with a NeRF.
Subsequently, a coarse mesh is extracted, and an iterative surface refinement algorithm is developed to adaptively adjust both vertex positions and face density based on re-projected rendering errors.
We jointly refine the appearance with geometry and bake it into texture images for real-time rendering.
Extensive experiments demonstrate that our method achieves superior mesh quality and competitive rendering quality.
