摘要:

三维场景局部编辑是内容生成的重要任务,在影视后期处理、数字孪生及游戏开发等领域具有显著的应用价值。三维高斯泼溅(3DGS)作为代表技术,在实时渲染方面取得关键突破,为高效编辑提供了有力支撑。现有基于扩散模型的三维高斯场景局部纹理编辑方法普遍存在的语义泄露与背景漂移问题,制约编辑质量。为此,提出一种基于语义引导区域自适应的三维场景局部纹理编辑方法。该方法旨在实现高质量纹理编辑的同时,保持非编辑区域的几何与外观一致性。首先,提出高置信度三维语义掩膜生成模块,引入视觉-语言大模型,利用LangSAM 与置信度过滤策略,通过多视角投票机制构建鲁棒的三维语义场,从源头消除语义泄露。其次,提出显著性引导的锚点视角传播模块,通过语义显著性评分自动选择最优锚点视角,配合多视角注意力一致性机制有效抑制时序闪烁。最后,提出区域自适应梯度更新策略,通过解耦前景编辑损失与背景锚定损失,对场景进行精细化优化。在Instruct-NeRF2NeRF和Mip-NeRF 360等数据集的5个编辑任务上的实验表明,与GaussianEditor和DGE等基线方法相比,该方法在CLIP Score,Background LPIPS,Background PSNR和Temporal LPIPS等定量指标上综合表现更优。在定性评估中,该方法不仅在复杂语义解耦与背景保护任务上呈现出综合性优势,还在纹理质量与几何完整性之间取得了较好的平衡。

Abstract:

Local editing of 3D scenes constitutes a fundamental task in content generation, with substantial application value in domains such as post-production, digital twins, and game development. 3D Gaussian Splatting (3DGS), as a representative technique, has achieved pivotal breakthroughs in real-time rendering, thereby providing robust support for efficient editing workflows. Nevertheless, existing diffusion-based methods for local texture editing of 3D Gaussian scenes are commonly plagued by semantic leakage and background drift, which limit editing fidelity. To tackle these challenges, a semantically guided region-adaptive approach was proposed for local texture editing of 3D scenes. The proposed method was designed to deliver high-quality texture editing while rigorously preserving the geometric and appearance consistency of non-edited regions. Concretely, a high-confidence 3D semantic mask generation module was first introduced, which incorporates a vision-language foundation model, employs LangSAM in conjunction with a confidence-filtering strategy, and constructs a robust 3D semantic field via multi-view voting, thereby eliminating semantic leakage at its source. Subsequently, a saliency-guided anchor view propagation module was devised, which automatically selects optimal anchor views based on semantic saliency scores and integrates a multi-view attention consistency mechanism to effectively mitigate temporal flickering. Finally, a region-adaptive gradient update strategy was formulated, which decouples the foreground editing loss from the background anchoring loss, enabling fine-grained scene optimization. Experiments conducted on five editing tasks across the Instruct-NeRF2NeRF and Mip-NeRF 360 datasets demonstrated that, when compared with baseline methods such as GaussianEditor and DGE, the proposed method performed better overal on quantitative metrics such as CLIP Score, Background LPIPS, Background PSNR, and Temporal LPIPS. Qualitative evaluation further showed that the proposed method not only exhibited overall advantages in complex semantic decoupling and background preservation tasks, but also achieved a favorable balance between texture quality and geometric integrity.
