Remote Sens., vol.8, no.6, p.501,2016. (http://www.mdpi.com/2072-4292/8/6/501/htm)

In the development of our package, we reference to CSF(git@github.com:jianboqi/CSF.git).

3. PCL1.8
4. JsonCpp

Build

Clont the repository and make:

git clone git@github.com:chronofei/ground_filter.git ground_filter
cd ground_filter
mkdir build
cd build
cmake ..
make -j8

Run

source build/devel/setup.bash
cd launch

Additional Notes

1. The package name in the offline.launch needs to be specified as yours.
2. When using, you need to adjust the parameters in the config/*.json to suit your lidar
