单视图编辑即可同步调整多视角光照,保持一致性。

SyncLight: Single-Edit Multi-View Relighting

  • 用多视角扩散变换器+隐空间桥接训练,实现单次推理全场景重光照。
  • 仅需一个参考视图编辑,就能零样本推广到任意多视角。
  • 适合影视虚拟制作、多机位直播等需一致光照的场景。

我们提出SyncLight,一种在单个参考视图编辑基础上,对静态场景的多个未标定视角实现一致且参数化光照控制的方法。尽管单视图重光照已取得显著进展,现有生成方法难以满足多摄像机广播、立体电影和虚拟制作所需的严格光照一致性要求。SyncLight通过多视角扩散变压器结合隐空间桥接匹配训练,可在一次推理中高保真地完成整个图像集的重光照。为支持训练,我们构建了一个大规模混合数据集,包含来自现有资源与新设计的多样化合成环境,以及在标定光照下的高保真真实多视角捕获。尽管训练仅基于图像对,SyncLight可零样本泛化至任意数量视角,有效传播光照变化,无需相机位姿信息。该方法为多视角捕获系统提供了实用的重光照工作流。

原文摘要 · Abstract (English)

We present SyncLight, a method to enable consistent, parametric control over light sources across multiple uncalibrated views of a static scene conditioned on a single view. While single-view relighting has advanced significantly, existing generative approaches struggle to maintain the rigorous lighting consistency essential for multi-camera broadcasts, stereoscopic cinema, and virtual production. SyncLight addresses this by enabling precise control over light intensity and color across a multi-view capture of a scene, conditioned on a single reference edit. Our method leverages a multi-view diffusion transformer trained using a latent bridge matching formulation, achieving high-fidelity relighting of the entire image set in a single inference step. To facilitate training, we introduce a large-scale hybrid dataset comprising diverse synthetic environments -- curated from existing sources and newly designed scenes -- alongside high-fidelity, real-world multi-view captures under calibrated illumination. Though trained only on image pairs, SyncLight generalizes zero-shot to an arbitrary number of viewpoints, effectively propagating lighting changes across all views, without requiring camera pose information. SyncLight enables practical relighting workflows for multi-view capture systems.
