Researchers have developed GenSfM, a novel method that combines structure-from-motion (SfM) techniques with 3D diffusion models to reconstruct 3D objects and camera poses from uncalibrated images. This approach aims to overcome the limitations of traditional SfM, which cannot infer unseen regions, and native generation methods, which may not be faithful to input images. By jointly denoising shape and pose latents, GenSfM grounds generated geometry in observed views while using object-level priors to infer unobserved areas, achieving significant improvements in novel-view synthesis and reducing reconstruction error on benchmark datasets.
