Coverage planning in general polygons with holes.
This package contains implementations to compute coverage patterns and shortest paths in general polygon with holes. Please cite our accompanying publication when using it.

Install ROS noetic. Install mono.
Create a workspace and download the package.
cd ~
mkdir -p catkin_ws/src
cd catkin_ws
catkin init
catkin config --cmake-args -DCMAKE_BUILD_TYPE=Release
catkin config --extend /opt/ros/noetic
cd src
git clone [email protected]:ethz-asl/polygon_coverage_planning.git
Install all remaining dependencies:
cd polygon_coverage_planning/install
./prepare-jenkins-slave.sh
Finally, build the workspace.
catkin build
The package has a ROS interface for shortest path planning and coverage planning. First source your workspace to execute any of the nodes.
source ~/catkin_ws/devel/setup.bash
roslaunch polygon_coverage_ros coverage_planner.launch
The polygon can be set via
rosservice call /coverage_planner/set_polygon
/coverage_planner/polygon
orThe plan is generated via
rosservice call /coverage_planner/plan_path
orThe resulting waypointlist is published as geometry_msgs/PoseArray on topic /waypoint_list
.
To publish the waypoint list
rosservice call /coverage_planner/publish_path_points
orpublish_plan_on_planning_complete: true
in coverage.yaml
roslaunch polygon_coverage_ros shortest_path_planner.launch
Setting the polygon and planning the path is the same as for Coverage Planning.
