通过智能管理高斯点属性,实现更逼真的场景重建。

Effective Gaussian Management for High-fidelity Scene Reconstruction

  • 分阶段激活颜色与法向属性,缓解优化冲突。
  • 自适应调整球谐阶数并分任务剪枝,减少冗余。
  • 兼容多种架构,参数少却效果优,适合高效重建。

本文提出一种高效的高保真场景重建高斯管理框架,针对现有高斯溅射(GS)流程对所有基元统一处理的问题,显式管理高斯点的属性激活、表示与剪枝。首先引入GauSep,一种选择性激活颜色或法向属性的新型稠密化策略,以缓解双监督带来的破坏性梯度冲突。进一步提出GauRep,一种自适应高斯表示方法,动态调整球谐(SHs)阶数,并执行任务解耦剪枝,从个体与全局层面降低冗余。为保障上述管理过程的几何监督可靠性,额外设计CoRe模块,通过置信度机制将SDF分支中的鲁棒法向场蒸馏至高斯表示。所提方法兼容多种重建架构,可无缝集成提升性能同时显著压缩模型规模。大量实验表明,该方法在外观与几何重建上优于或相当当前最优方法,且参数量大幅减少。

原文摘要 · Abstract (English)

This paper proposes an effective Gaussian management framework for high-fidelity scene reconstruction of both appearance and geometry. Unlike recent Gaussian Splatting (GS) pipelines that treat all primitives uniformly during optimization, our framework explicitly manages the attribute activation, representation and pruning of Gaussian. Specifically, our framework first introduces GauSep, a novel densification strategy that selectively activates Gaussian color or normal attributes to alleviate destructive gradient conflicts arising from dual supervision. We further propose GauRep, an adaptive Gaussian representation that dynamically adjusts spherical harmonics (SHs) orders and performs task-decoupled pruning to reduce redundancy at both the individual and global levels. To provide reliable geometric supervision for above mangement process, we additionally introduce CoRe, an regularized surface reconstruction module that distills robust normal fields from an SDF branch to the Gaussian representation through a confidence mechanism. Notably, the proposed Gaussian management is compatible with various reconstruction architectures and can be seamlessly integrated to improve performance while reducing size of the model. Extensive experiments demonstrate that our approach achieves superior or comparable performance in appearance and geometry reconstruction compared with state-of-the-art methods, while using significantly fewer parameters.
