Overview

A 3D framework

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

This framework is intended for massive DSM production with a robust, performant and modular design.

It is mainly composed of:

• Command line configured through a Configuration file.

• Pipelines:

  • Sensor to full resolution dsm main pipeline: end-to-end processing pipeline from sensor images to full DSM

  • Sensor to low resolution_dsm: subpart of the previous, pipeline based on sparse matches to generate a low resolution DSM

• Python 3D API: composed of well known steps in Multiview Stereo Pipeline divided in Applications for each 3D steps used by pipelines.

Computing distribution

The chain have computing distribution capabilities and can use dask (local or distributed cluster) or multiprocessing libraries to distribute the computations. The distributed cluster require centralized files storage and uses PBS scheduler only for now.
