OpenSfM

OpenSfM is a powerful open-source Structure-from-Motion (SfM) pipeline designed for generating 3D reconstructions from photographic imagery. Developed by Mapillary, this robust toolkit processes sets of images to identify features, estimate camera positions, and reconstruct dense 3D point clouds and models of scenes.

The pipeline is instrumental in various geospatial applications, allowing users to create detailed digital representations of real-world environments. Its capabilities are particularly valuable for tasks requiring accurate 3D mapping, surveying, and environmental monitoring using standard camera inputs. Being open-source, it fosters collaborative development and provides a flexible platform for researchers and developers.

This project provides a comprehensive set of functionalities for the entire SfM workflow, from feature detection and matching to bundle adjustment and dense reconstruction. It represents a key resource for anyone looking to implement photogrammetric workflows or integrate 3D reconstruction capabilities into their own software solutions, often leveraging programming languages like Python.
