| 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:
CARS is available on Docker Hub and can be downloaded by:
docker pull cnes/carsYou 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"
}
}
},
"output": {
"directory": "outresults"
}
}
