openMVG

openMVG is a powerful, open-source C++ library dedicated to Multiple View Geometry (MVG). It serves as a foundational toolkit for various 3D computer vision applications, with a primary focus on Structure from Motion (SfM). This library enables users to reconstruct detailed 3D models and environments from a collection of 2D images, capturing the geometry of scenes and objects.

The library integrates a suite of algorithms essential for SfM pipelines, including feature detection and matching, camera pose estimation, and dense point cloud generation. Its modular design allows developers to leverage specific components for their projects or utilize the complete pipeline for comprehensive 3D reconstruction. This makes openMVG a valuable asset for researchers, developers, and practitioners in fields requiring precise 3D data from imagery.

Built with an emphasis on performance and flexibility, openMVG supports various input data types and provides command-line tools for ease of use. It is widely adopted in academic and industrial settings for tasks ranging from cultural heritage preservation and archaeological documentation to drone mapping and virtual reality content creation, offering a robust platform for turning images into accurate 3D representations.
