Photogrammetry

Photogrammetry is the science of making measurements from photographs. It infers the geometry of a scene from a set of unordered photographs or videos. Photography is the projection of a 3D scene onto a 2D plane, losing depth information. The goal of photogrammetry is to reverse this process.

See the presentation of the pipeline steps.

Get the project

You can download pre-compiled binaries for the latest release.

If you want to build it yourself, see INSTALL.md to setup the project and pre-requisites.

Get the source code and install runtime requirements:

git clone --recursive git://github.com/alicevision/meshroom
cd meshroom
pip install -r requirements.txt

Start Meshroom

You need to have AliceVision installation in your PATH (and LD_LIBRARY_PATH on Linux/macOS).

• Launch the User Interface

# Windows
set PYTHONPATH=%CD% && python meshroom/ui
# Linux/macOS
PYTHONPATH=$PWD python meshroom/ui

On Ubuntu, you may have conflicts between native drivers and mesa drivers. In that case, you need to force usage of native drivers by adding them to the LD_LIBRARY_PATH: LD_LIBRARY_PATH=/usr/lib/nvidia-340 PYTHONPATH=$PWD python meshroom/ui You may need to adjust the folder /usr/lib/nvidia-340 with the correct driver version.

• Launch a 3D reconstruction in command line

# Windows: set PYTHONPATH=%CD% &&
# Linux/macOS: PYTHONPATH=$PWD
python bin/meshroom_batch --input INPUT_IMAGES_FOLDER --output OUTPUT_FOLDER

Start Meshroom without building AliceVision

To use Meshroom (ui) without building AliceVision

• Download a release
• Checkout corresponding Meshroom (ui) version/tag to avoid versions incompatibilities
• LD_LIBRARY_PATH=~/foo/Meshroom-2023.1.0/aliceVision/lib/ PATH=$PATH:~/foo/Meshroom-2023.1.0/aliceVision/bin/ PYTHONPATH=$PWD python3 meshroom/ui

Start and Debug Meshroom in an IDE

PyCharm Community is free IDE which can be used. To start and debug a project with that IDE, right-click on Meshroom/ui/__main__.py > Debug, then Edit Configuration, in Environment variables :

• If you want to use aliceVision built by yourself add: PATH=$PATH:/foo/build/Linux-x86_64/
• If you want to use aliceVision release add: LD_LIBRARY_PATH=/foo/Meshroom-2023.1.0/aliceVision/lib/;PATH=$PATH:/foo/Meshroom-2023.1.0/aliceVision/bin/ (Make sure that you are on the branch matching the right version)
