🎞️ From Stereo Images Input stereo image pairs

🌍 To Digital Surface Model (DSM) Output 3D surface reconstruction

CARS is an open source 3D tool dedicated to produce Digital Surface Models from satellite imaging by photogrammetry. This Multiview Stereo framework is intended for massive DSM production with a robust, performant and modular design.

CARS is currently under active development and integrated into various projects & missions:

Its roadmap and implemented functionalities are evolving regularly depending on specific project requirements.

You want to build the pyramids by yourself?

Download our open licence Pleiades data sample to give CARS a try!

CARS is available on Docker Hub and can be downloaded by:

docker pull cnes/cars

You only need to launch one command:

docker run -w /data -v "$(pwd)"/data_gizeh:/data cnes/cars /data/configfile.yaml

CARS can also be downloaded using the pip install command:

pip install cars 

Once you moved to the data_gizeh directory:

cars configfile.yaml
