Researchers have developed a new method to improve 3D reconstruction from sparse and noisy internet photos, addressing the challenge of the "long-tail" distribution where most sites have limited imagery. They created MegaDepth-X, a dataset of 3D reconstructions with dense depth, and a strategy for sampling training images that mimic sparse scenes. This approach enables more robust 3D reconstructions even with extreme data sparsity and improves performance on symmetric or repetitive structures. AI
