CARS is a dedicated and open source 3D tool to produce Digital Surface Models from satellite imaging by photogrammetry.

What it solves

CARS provides a way to generate Digital Surface Models (DSM) from satellite imagery. It addresses the need for a robust, performant, and modular framework capable of massive 3D surface reconstruction through photogrammetry.

How it works

It functions as a Multiview Stereo framework that processes input stereo image pairs from satellites to produce a 3D surface reconstruction (DSM). The system is designed for scalability and performance, allowing users to run the pipeline via a configuration file using either Docker or a pip installation.

Who it’s for

This tool is designed for researchers and engineers working with satellite imaging, photogrammetry, and global 3D reconstruction projects.

Highlights

  • Massive DSM production capabilities
  • Modular and robust design
  • Supports deployment via Docker or pip
  • Integrated into various international projects like AI4GEO and CO3D
