CARS is a dedicated and open source 3D tool to produce Digital Surface Models from satellite imaging by photogrammetry. This Multiview stereo pipeline is intended for massive DSM production with a robust and performant design. CARS means CNES Algorithms to Reconstruct Surface (or Chaîne Automatique de Restitution Stéréoscopique in french)
It is composed of:
- A Python API, based on xarray, enabling to realize all the computation steps leading to a DSM.
- An end-to-end processing chain based on this API. It can be performed using dask (locally or on a cluster which has a GPFS centralized files storage) or multiprocessing libraries to distribute the computations.
