Photogrammetry has emerged as a vital tool for the generation of 3D models, point clouds, camera poses, and geospatial data from overlapping photographs. From drones to 3D reconstructions and computer vision, all forms of photogrammetry processes rely on the availability of software packages that can extract geometry from photographs. OpenMVG (Open Multiple View Geometry) is an open-source computer vision library that aims at providing the fundamental algorithms for Multiple View Geometry (MVG) and image-based 3D reconstruction.
