COLMAP adapted from COLMAP 3.4 (see original read me below). Have added semantic segmentations to 3D reconstructions as an additional color channel.

Below starts original README.

COLMAP

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. The software is licensed under the GNU General Public License.

The latest source code is available at https://github.com/colmap/colmap. COLMAP builds on top of existing works and when using specific algorithms within COLMAP, please also cite the original authors, as specified in the source code.

Download

Executables for Windows and Mac and other resources can be downloaded from https://demuc.de/colmap/. Executables for Linux/Unix/BSD are available at https://repology.org/metapackage/colmap/versions. To build COLMAP from source, please see https://colmap.github.io/install.html.

Getting Started

  1. Download the pre-built binaries from https://demuc.de/colmap/ or build the library manually as described in the documentation.
  2. Download one of the provided datasets at https://demuc.de/colmap/datasets/ or use your own images.
  3. Use the automatic reconstruction to easily build models with a single click or command.
  4. Watch the short introductory video at https://www.youtube.com/watch?v=P-EC0DzeVEU or read the tutorial in the documentation at https://colmap.github.io/ for more details.
