## Overview

From stereo images  |  CARS produces a Digital Surface Model (DSM)
:-------------------------:|:-------------------------:

**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.

Be aware that the project is new and is evolving to maturity with CNES usage roadmaps and projects such as:
- <a href="https://co3d.cnes.fr/en/co3d-0">CO3D project &nbsp;&nbsp;&nbsp;  <img src="https://raw.githubusercontent.com/CNES/cars/master/docs/source/images/logo_co3D_cnes.jpg" width="20" height="20"/></a>

## Quick start

### CARS Docker Image

[![Docker Status](http://dockeri.co/image/cnes/cars)](https://hub.docker.com/r/cnes/cars)

CARS is available on Docker Hub and can be downloaded by:
``` bash
docker pull cnes/cars
```

### One main pipeline to generate DSM

You only need to launch one command:

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

with one configuration input file ("configfile.json") located in a "data" folder to be consistent with the previous command lines:
```
{

        "inputs": {
            "sensors" : {
                "one": {
                    "image": "img1.tif",
                    "geomodel": "img1.geom"
                },
                "two": {
                    "image": "img2.tif",
                    "geomodel": "img2.geom"
                },
                "three": {
                    "image": "img3.tif",
                    "geomodel": "img3.geom"
                }
            },
            "pairing": [["one", "two"],["one", "three"]],
            "initial_elevation": "srtm_dir/N29E031_KHEOPS.tif"
        },

        "output": {
              "out_dir": "outresults"
        }

}

```

### On the way to the Pyramids...
