本期带来上周在arXiv公开的论文15篇，涉及3D重建、3D生成、3D编辑、4D生成。 一、3D重建 1.[2024-arXiv] Splatt3R: Zero-shot Gaussian Splatting from Uncalibrated Image Pairs 作者机构：Brandon Smart, et al. University of Oxford 论文地址： https://arxiv.org/pdf/2408.13912 项目地址： https://splatt3r.active.vision/ 贡献： We introduce Splatt3R, a pose-free, feedforward method for in-the-wild 3D reconstruction and novel view synthesis from stereo pairs. For generalizability, we build Splatt3R upon a “foundation” 3D geometry reconstruction method, MASt3R, by extending it to deal with both 3D structure and appearance. Splatt3R can reconstruct scenes at 4FPS at 512×512 resolution, and the resultant splats can be rendered in real-time. 2.[2024-arXiv] 3D Reconstruction with Spatial Memory 作者机构：Hengyi Wang, Lourdes Agapito.
