Semantic gaussian splatting-enhanced facility management within the framework of IFC-graph

Abstract

The indoor environment of as-built structures undergo modifications over time, deviating from their original design and complicating facility management. Existing methods struggle to produce high-fidelity 3D models to represent that change. Gaussian splatting, a recent reconstruction technique, enables real-time rendering with high visual quality, offering a promising solution. This paper proposes a method that generates semantic Gaussian splats from panoramic images and integrates them into an IFC-graph for facility management. The approach enhances facility recognition and retrieval while enabling high-fidelity rendering of indoor environments. A case study demonstrates two key applications: semantic-guided facility retrieval and high-fidelity rendering, improving the semantic richness and visual quality of as-built BIM models
