Abstract

In recent years, Neural Radiance Fields (NeRFs) and 3D Gaussian Splatting (3DGS) have emerged as promising new approaches for 3D reconstruction. NeRFs rely on neural fields that generate a three-dimensional representation of a scene from photographs, estimating reflectance properties and reconstructing the underlying geometry. Since their introduction in 2020, NeRFs have attracted significant attention due to their wide range of potential applications. Conversely, 3D Gaussian Splatting (3DGS), introduced in 2023, employs Gaussian primitives to efficiently model objects and structures, offering a flexible and adaptive representation of 3D scenes. Starting from an established pipeline for the use of reality-based models for structural analysis, this paper investigates the performance of 3DGS in handling complex geometries and surfaces characterised by challenging acquisition conditions.
