Semantic assisted Normal Distributions Transform

Point cloud registration and loop closure detection.

How to run the code.

Dependencies: Boost, Eigen, PCL, Ceres solver

Build with:

git clone --recurse-submodules https://github.com/azaganidis/se_ndt
mkdir se_ndt/build
cd se_ndt/build
cmake -DCMAKE_BUILD_TYPE=Release -DWITH_GL=True ..
make -j4

Example use on KITTI using the labels from RangeNet++ download

./kitti_slam -p /mnt/external/Datasets/kitti/sequences/00/velodyne/* -l /mnt/external/Datasets/kitti/darknet53-knn/darknet53-knn/sequences/00/predictions/* -v

To visualize the map, press any key in the NDTVizGlut window. Exit with q. The mapping results are written in pose_graph_out.txt.
