COLMAP is a general-purpose Structure-from-Motion (SfM) and Multi-View Stereo (MVS) pipeline with a graphical and command-line interface. It offers a wide range of features for reconstruction of ordered and unordered image collections. The software is licensed under the new BSD license.

COLMAP was originally written by Johannes Schönberger with funding provided by his PhD advisors Jan-Michael Frahm and Marc Pollefeys.
The Python bindings in PyCOLMAP were originally added by Mihai Dusmanu, Philipp Lindenberger, and Paul-Edouard Sarlin.
The project has also benefitted from countless community contributions, including bug fixes, improvements, new features, third-party tooling, and community support (special credits to Torsten Sattler).
Contributions (bug reports, bug fixes, improvements, etc.) are very welcome and should be submitted in the form of new issues and/or pull requests on GitHub.
