PatchScene: Patch-based Voxel Diffusion for Large-Scale Scene Completion

arXiv CS.CV

ArXi:2606.03915v1 Announce Type: new We propose PatchScene, a novel diffusion-based framework for large-scale LiDAR scene completion. Unlike existing methods that rely on global latent representations or dense voxel grids, PatchScene adopts a patch-based voxel diffusion paradigm that explicitly generates fine-grained geometry within localized 3D regions. To ensure coherent reconstruction at both spatial and temporal scales, we
