• Abstract: Photo-realistic novel view synthesis from multi-view images, such as neural radiance field (NeRF) and 3D Gaussian Splatting (3DGS), has gained significant attention for its superior performance. However, most existing methods rely on low dynamic range (LDR) images, limiting their ability to capture detailed scenes in high-contrast environments. While some prior works address high dynamic range (HDR) scene reconstruction, they typically require multi-view sharp images with varying exposure times captured at fixed camera positions, which is time-consuming and impractical. To make data acquisition more flexible, we propose \textbf{Casual3DHDR}, a robust one-stage method that reconstructs 3D HDR scenes from casually-captured auto-exposure (AE) videos, even under severe motion blur and unknown, varying exposure times. Our approach integrates a continuous-time camera trajectory into a unified physical imaging model, jointly optimizing exposure times, camera trajectory, and the camera response function (CRF). Extensive experiments on synthetic and real-world datasets demonstrate that \textbf{Casual3DHDR} outperforms existing methods in robustness and rendering quality.

• HDRSplat: Gaussian Splatting for High Dynamic Range 3D Scene Reconstruction from Raw Images [14.332077246864628]
  3D Gaussian Splatting (3DGS) has revolutionized the 3D scene reconstruction space enabling high-fidelity novel view in real-time. However, prior 3DGS and NeRF-based methods rely on 8-bit tone-mapped Low Dynamic Range images for scene reconstruction. Our proposed method HDRSplat tailors 3DGS to train directly on 14-bit linear raw images in near darkness which preserves the scenes' full dynamic range and content.

  Radiance field methods represent the state of the art in reconstructing complex scenes from multi-view photos.

We present a lightweight analytical based on 3D Gaussian Splatting that utilizes multi-view LDR images on varying exposure times, radiance of apertures, and focus distances as input to reconstruct a high-dynamic-range scene.
