Installation

You can either download one of the pre-built binaries from https://demuc.de/colmap/ or build the source code manually.

Pre-built Binaries

Windows

For convenience, the pre-built binaries for Windows contain both the graphical and command-line interface executables. To start the COLMAP GUI, you can simply run the COLMAP.bat batch script. The command-line executables are located in the bin folder and can be run from the Windows command shell cmd.exe.

Mac

The pre-built binaries for Mac only contains the GUI version of COLMAP, since it is very easy to compile COLMAP yourself. COLMAP is shipped as an unsigned application, i.e., you have to right-click the application and select Open and then accept to trust the application. In the future, you can then simply double-click the application to open COLMAP.

Build from Source

COLMAP builds on all major platforms (Linux, Mac, Windows) with little effort. First, checkout the latest source code:

git clone https://github.com/colmap/colmap

The latest stable version lives in the master branch and the latest development version lives in the dev branch. Next, follow the build instructions for your platform as detailed below.

Linux

Recommended dependencies: CUDA.

Dependencies from default Ubuntu 14.04/16.04 repositories:

sudo apt-get install \
    cmake \
    build-essential \
    libboost-all-dev \
    libeigen3-dev \
    libsuitesparse-dev \
    libfreeimage-dev \
    libgoogle-glog-dev \
    libgflags-dev \
    libglew-dev \
    qt5-default

Install Ceres Solver:

sudo apt-get install libatlas-base-dev libsuitesparse-dev
git clone https://ceres-solver.googlesource.com/ceres-solver
cd ceres-solver
mkdir build
cd build
cmake .. -DBUILD_TESTING=OFF -DBUILD_EXAMPLES=OFF
make -j
sudo make install

Configure and compile COLMAP:

cd path/to/colmap
mkdir build
cd build
cmake ..
make -j

Mac

Recommended dependencies: CUDA.

Dependencies from Homebrew:

brew tap homebrew/science
brew install \
    cmake \
    boost \
    eigen \
    freeimage \
    glog \
    gflags \
    suite-sparse \
    ceres-solver \
    qt5 \
    glew

Create the file LocalConfig.cmake in the COLMAP base directory and then insert the following lines into it:

set(Qt5_CMAKE_DIR "/usr/local/opt/qt5/lib/cmake")
set(Qt5Core_DIR ${Qt5_CMAKE_DIR}/Qt5Core)
set(Qt5OpenGL_DIR ${Qt5_CMAKE_DIR}/Qt5OpenGL)

Configure and compile COLMAP:

cd path/to/colmap
mkdir build
cd build
cmake ..
make -j

Windows

On Windows you have to install the above dependencies manually. To make the process of configuring CMake less painful, please have a look at LocalConfigExample.config. MSVC12 (Microsoft Visual Studio 2013) and newer are confirmed to compile COLMAP without any issues.

Recommended dependencies: CUDA.

Documentation

You need Python and Sphinx to build the HTML documentation:

cd path/to/colmap/doc
sudo apt-get install python
pip install sphinx
make html
open _build/html/index.html

Alternatively, you can build the documentation as PDF, EPUB, etc.:

make latexpdf
open _build/pdf/COLMAP.pdf
