The source code is available at https://github.com/colmap/colmap. COLMAP builds on top of existing work and when using specific algorithms within COLMAP, please also consider citing the original works, as specified in the source code.
- Download the pre-built binaries from http://people.inf.ethz.ch/jschoenb/colmap/ or build the library manually as described in the documentation.
- Download one of the provided datasets at http://people.inf.ethz.ch/jschoenb/colmap/datasets/.
- Watch the short introductory video at https://www.youtube.com/watch?v=P-EC0DzeVEU or read the tutorial in the documentation for more details.
The documentation is available at https://colmap.github.io/.
Please, use the GitHub issue tracker at https://github.com/colmap/colmap for bug reports, questions, suggestions, etc.
The library was written by Johannes L. Schönberger (http://people.inf.ethz.ch/jschoenb/). Funding was provided by his PhD advisor Jan-Michael Frahm (http://frahm.web.unc.edu/) through the grants NSF No. IIS-1349074, No. CNS-1405847, and the MITRE Corp.
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.
Please, adhere to the Google coding style guide:
http://google-styleguide.googlecode.com/svn/trunk/cppguide.html
by using the provided ".clang-format" file.
Document functions, methods, classes, etc. with inline documentation strings describing the API, using the following format:
// Short description.
//
// Longer description with a few sentences and multiple lines.
//
// @param parameter1 Description for parameter 1.
// @param parameter2 Description for parameter 2.
//
// @return Description of optional return value.
Add unit tests for all newly added code and make sure that algorithmic "improvements" generalize and actually improve the results of the pipeline on a variety of datasets.
