If you are not familiar with ROS, please visit the original repository.

If you follow the repository, you can run Patchwork++ in Python and C++ easily.

:package: Prerequisite packages

You may need to install ROS, PCL, Eigen, ...

:gear: How to build Patchwork++

To build Patchwork++, you can follow below codes.

$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws
$ catkin build # or catkin_make

:runner: To run the demo codes

There is a demo which executes Patchwork++ with sample rosbag file. You can download a sample file with the following command.

For the sample rosbag data, I utilizes semantickitti2bag package.

$ wget https://urserver.kaist.ac.kr/publicdata/patchwork++/kitti_00_sample.bag

If you have any trouble to download the file by the above command, please click here to download the file directly.

The rosbag file is based on the KITTI dataset. The bin files are merged into the rosbag file format.

The sample file contains LiDAR sensor data only.

Then, you can run demo as follows.

# Start Patchwork++
$ roslaunch patchworkpp demo.launch
# Start the bag file
$ rosbag play kitti_00_sample.bag
