probabilistic_occupancy_grid_map
Purpose
This package outputs the probability of having an obstacle as occupancy grid map.

References/External links
Settings
Occupancy grid map is generated on map_frame, and grid orientation is fixed.
You may need to choose scan_origin_frame and gridmap_origin_frame which means sensor origin and gridmap origin respectively. Especially, set your main LiDAR sensor frame (e.g. velodyne_top in sample_vehicle) as a scan_origin_frame would result in better performance.
Each config parameters
Config parameters are managed in config/*.yaml and here shows its outline.

probabilistic_occupancy_grid_map
Purpose
This package outputs the probability of having an obstacle as occupancy grid map.

Settings
Occupancy grid map is generated on map_frame, and grid orientation is fixed.
You may need to choose scan_origin_frame and gridmap_origin_frame which means sensor origin and gridmap origin respectively. Especially, set your main LiDAR sensor frame (e.g. velodyne_top in sample_vehicle) as a scan_origin_frame would result in better performance.

Config parameters are managed in config/*.yaml and here shows its outline.
