OpenMVG
What it is
OpenMVG is a multiple-view geometry library for 3D computer vision and structure-from-motion work. It provides an end-to-end framework for reconstructing 3D scenes from images, using libraries, binaries, and processing pipelines. Its libraries cover image manipulation, feature description and matching, feature tracking, camera models, multiple-view geometry, robust estimation, and structure-from-motion algorithms. Binaries support scene initialization, feature detection and matching, reconstruction, and scene export to other multiple-view-stereo frameworks. Those frameworks can compute dense point clouds or textured meshes from exported scenes. OpenMVG is written in C++ and licensed under the Mozilla Public License 2.0. The project says it aims to support reproducible research with readable implementations of classic and state-of-the-art algorithms. It is designed to be read, learned from, modified, and used, and includes test-driven development and samples. Tutorials cover data structures, library use, and processing an image dataset. The project is free and open source, with desktop deployment listed and platforms including Windows, macOS, Linux, iOS, and Android. It provides API access and lists point cloud export and ground control point support.
