SAIL-Recon
Sail-Recon is a feed-forward Transformer that scales neural scene regression to large-scale Structure-from-Motion by augmenting it with visual localization. From a few anchor views, it constructs a global latent scene representation that encodes both geometry and appearance. Conditioned on this representation, the network directly regresses camera poses, intrinsics, depth maps, and scene coordinate maps for thousands of images in minutes, enabling precise and robust reconstruction without iterative optimization.
