DiffusionSfM: Predicting Structure and Motion via Ray Origin and Endpoint Diffusion

CVPR 2025poster

Current Structure-from-Motion (SfM) methods typically follow a two-stage pipeline, combining learned or geometric pairwise reasoning with a subsequent global optimization step. In contrast, we propose a data-driven multi-view reasoning approach that directly infers 3D scene geometry and camera poses…

Cameras as Rays: Pose Estimation via Ray Diffusion

ICLR 2024oral

Estimating camera poses is a fundamental task for 3D reconstruction and remains challenging given sparsely sampled views (<10). In contrast to existing approaches that pursue top-down prediction of global parametrizations of camera extrinsics, we propose a distributed representation of camera pose t…
