openMVG

Why we included this project

openMVG is a C++ library that recovers camera poses and a 3D point cloud from overlapping photos, with no requirement that your images arrive in any particular order. Its pipeline covers feature detection and matching, camera models, robust estimation, and the structure-from-motion stage itself, then exports results to other multi-view stereo tools for dense point clouds or textured meshes. That makes it a practical base for photogrammetry, drone mapping, and any project that needs to turn unordered imagery into geometry. The code is deliberately readable and ships with samples plus a test-driven build, so teams can pull individual modules into their own systems instead of committing to a black box. It builds for Android, iOS, Linux, macOS, and Windows, which matters when the reconstruction has to run on mobile or embedded targets.
