ABOUT

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.

GETTING STARTED

 1. Download the pre-built binaries or build the library manually from source
    (see Installation).

 2. Download one of the provided datasets (see Datasets) or use your own images.

 3. Use the automatic reconstruction to easily build models with a single click
    (see Quickstart).


SUPPORT

Please, use the Google Group (colmap@googlegroups.com) for questions and the
GitHub issue tracker for bug reports, feature requests/additions, etc.


ACKNOWLEDGMENTS

The library was written by Johannes L. Schönberger. Funding was provided by his
