OpenMVG is a library targeted at photogrammetry that is popular within the Multiple View Geometry (MVG) community and computer-vision scientists. It tends to focus on the structure from motion (SfM) technique of photogrammetry, with a number of the integrated tools built around this.
All its features and models are tested to make sure they work properly in real-life situations.
This photogrammetry pipeline requires compiling to use and takes some computer savvy to get up and running on Windows or Linux.
It’s designed around the mantra of “Keep it simple, keep it maintainable,” the community-focused accessibility of OpenMVG makes it an accessible tool that fits into the workflows of other photogrammetry tools.
