norlab_icp_mapper_ros

A bridge between norlab_icp_mapper and ROS. Check the mapper's documentation for a detailed guide.

Node Parameters

Name	Description	Possible values	Default Value
odom_frame	Frame used for odometry.	Any string	"odom"
robot_frame	Frame centered on the robot.	Any string	"base_link"
mapping_config	Path to the file containing the mapping config.	Any file path	""
initial_map_file_name	Path of the file from which the initial map is loaded.	Any file path	""
initial_robot_pose	Transformation matrix in homogeneous coordinates describing the initial pose of the robot in the map frame.	Any matrix of dimension 3 or 4	"[[1, 0, 0, 0], [0, 1, 0, 0], [0, 0, 1, 0], [0, 0, 0, 1]]"
final_map_file_name	Path of the file in which the final map is saved when is_online is false.	Any file path	"map.vtk"
final_trajectory_file_name	Path of the file in which the final trajectory is saved when is_online is false.	Any file path	"trajectory.vtk"
map_publish_rate	Rate at which the map is published (in Hertz). It can be slower depending on the map update rate.	(0, ∞)	10.0
map_tf_publish_rate	Rate at which the map tf is published (in Hertz).	(0, ∞)	10.0
max_idle_time	Delay to wait being idle before shutting down ROS when is_online is false (in seconds).	[0, ∞)	10.0
is_mapping	true when map updates are wanted, false when only localization is wanted.	{true, false}	true
is_online	true when online mapping is wanted, false otherwise.	{true, false}	true
is_3D	true when a 3D sensor is used, false when a 2D sensor is used.	{true, false}	true
save_map_cells_on_hard_drive	true when map cell storage on hard drive is wanted, false when map cell storage in RAM is wanted.	{true, false}	true
publish_tfs_between_registrations	When false, the map tf is published only after registration. Otherwise with map_tf_publish_rate.	{true, false}	true

Node Topics

Name	Description
points_in	Topic from which the input points are retrieved.
map	Topic in which the map is published.
icp_odom	Topic in which the corrected odometry is published.

Node Services

Name	Description	Parameter Name	Parameter Description
save_map	Saves the current map.	filename	Path of the file in which the map is saved.
save_trajectory	Saves the current trajectory.	filename	Path of the file in which the trajectory is saved.
reload_yaml_config	Reload the YAML config file.
