This is a point cloud clustering segmentation algorithm, including the removal of ground point clouds and the segmentation of point clouds.
You can use the following commands to download and compile the package.
cd ~/catkin_ws/src
https://github.com/supengufo/depth_clustre_ros
cd ..
caktin_make
run the launch file:
cd ~/catkin_ws
source devel/setup.bash(or setup.zsh)
roslaunch depth_cluster_ros depth_cluster_ros.launch
The main idea of point cloud segmentation is based on depth_cluster, in which the filtering threshold condition and neighborhood search are modified;
The segmentation of ground point clouds is based on Zermas' paper, although principal component analysis is already a very common method to extract ground.
Thank them for their work!
