| 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 Pipeline is intended for massive DSM production with a robust and performant 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 two commands:
# prepare step
docker run -v "$(pwd)"/data:/data cnes/cars prepare -i /data/input.json -o /data/prepare_outdir
# compute_dsm step
docker run -v "$(pwd)"/data:/data cnes/cars compute_dsm -i /data/prepare_outdir/content.json -o /data/compute_dsm_outdir
with one configuration input file ("input.json") located in a "data" folder to be consistent with the previous command lines:
{
"img1" : "img1.tif",
"color1" : "color1.tif",
"img2" : "img2.tif",
"srtm_dir" : "srtm_dir",
"nodata1": 0,
"nodata2": 0
}
You want to build the pyramids by yourself? Download our open licence Pleiades data sample to give CARS a try! You're at a dead end? This quick start script sets you back on the right path.
