openMVG

openMVG is an open-source library for multi-view geometry and structure from motion (SfM) that uses computer vision and machine learning techniques. It processes images to recover 3D models of scenes, enabling applications such as 3D reconstruction, photogrammetry, and augmented reality. Key features include robust algorithms for camera calibration, feature extraction, and dense and sparse reconstruction. For instance, it can be used to create 3D models of buildings or landscapes from a series of photos taken from different angles. It is best suited for researchers and professionals in the fields of computer vision, photogrammetry, and 3D modeling. Compared to commercial solutions, openMVG offers flexibility and customization but requires more technical expertise to use effectively.
