OpenMVG

openMVG is an open-source C++ library for multiple-view geometry, photogrammetry, and Structure from Motion. It provides an end-to-end framework for reconstructing 3D scenes from collections of ordinary images. Its libraries cover image handling, feature description, feature matching, feature tracking, camera models, triangulation, robust estimation, and geometric solvers. Command-line binaries handle individual reconstruction stages that can be combined into complete pipelines. Reconstructed scenes can be exported to other multi-view stereo tools for dense point clouds and textured meshes. The project emphasizes readable, maintainable implementations backed by tests and examples. It runs on Linux, macOS, Windows, Android, and iOS.
