DHGS: Decoupled Hybrid Gaussian Splatting for Driving Scene

Understand

Existing Gaussian splatting methods often fall short in achieving satisfactory novel view synthesis in driving scenes, primarily due to the absence of crafty designs and geometric constraints for the involved elements.

• This paper introduces a novel neural rendering method termed Decoupled Hybrid Gaussian Splatting (DHGS), targeting at promoting the rendering quality of novel view synthesis for static driving scenes.
• The novelty of this work lies in the decoupled and hybrid pixel-level blender for road and non-road layers, without the conventional unified differentiable rendering logic for the entire scene.
• Still, consistency and continuity in superimposition are preserved through the proposed depth-ordered hybrid rendering strategy.
