Researchers have developed InstantSfM, a novel GPU-native system for structure from motion (SfM) that integrates seamlessly with deep learning pipelines. Unlike traditional CPU-centric SfM methods, InstantSfM addresses scalability issues by embedding metric depth priors directly into its optimization framework, resolving scale ambiguity. This approach ensures numerical stability and achieves state-of-the-art efficiency, demonstrating up to a 40x speedup over COLMAP on large-scale scenes while maintaining comparable reconstruction accuracy.
