The task of extracting intrinsic components, such as reflectance and shading, from neural radiance fields is of growing interest. However, current methods largely focus on synthetic scenes and isolated objects, overlooking the complexities of real scenes with backgrounds. To address this gap, our research introduces a method that combines relighting with intrinsic decomposition. By leveraging light variations in scenes to generate pseudo labels, our method provides guidance for intrinsic decomposition without requiring ground truth data. Our method, grounded in physical constraints, ensures robustness across diverse scene types and reduces the reliance on pre-trained models or hand-crafted priors. We validate our method on both synthetic and real-world datasets, achieving convincing results. Furthermore, the applicability of our method to image editing tasks demonstrates promising outcomes.

我们的研究引入了一种将重照和内在分解相结合的方法，通过利用场景中的光变化生成伪标签，为内在分解提供指导，同时确保对不同场景类型的稳健性，并减少对预训练模型或手工先验的依赖。我们在合成和真实世界数据集上验证了我们的方法，并取得了令人信服的结果。此外，我们的方法在图像编辑任务中的适用性显示出了有希望的结果。
