StructureGS: Structure-aware Gaussian Splatting for Articulated Object Reconstruction

TL;DR - StructureGS adds explicit structural constraints to 3D Gaussian Splatting for reconstructing articulated objects. It improves part separation and geometry by modeling spatial coherence and physically plausible connections between movable parts.

• Uses oriented bounding boxes to guide reconstruction of individual object parts.
• Enforces compact, spatially coherent geometry within each part’s designated region.
• Adds connectivity constraints to preserve plausible contact between adjacent parts.
• Reportedly achieves state-of-the-art reconstruction quality with sharper part boundaries and fewer geometric artifacts.
