The costmap_generator Package#

costmap_generator_node#

This node reads PointCloud and/or DynamicObjectArray and creates an OccupancyGrid and GridMap. VectorMap(Lanelet2) is optional.

Input topics#

Name Type Description
~input/objects autoware_perception_msgs::DynamicObjectArray predicted objects, for obstacles areas
~input/points_no_ground sensor_msgs::PointCloud2 ground-removed points, for obstacle areas which can't be detected as objects
~input/vector_map autoware_lanelet2_msgs::MapBin vector map, for drivable areas
~input/scenario autoware_planning_msgs::Scenario scenarios to be activated, for node activation

Output topics#

Name Type Description
~output/grid_map grid_map_msgs::GridMap - costmap as GridMap, values are from 0.0 to 1.0
~output/occupancy_grid nav_msgs::OccupancyGrid - costmap as OccupancyGrid, values are from 0 to 100

Output TFs#

None
