mrpt_map_server

Table of Contents

Overview

This package provides a ROS 2 node that publishes a static map for other nodes to use it. Unlike classic ROS 1 map_server, this node can publish a range of different metric maps, not only occupancy grids.

Node: mrpt_map_server

Working rationale

The C++ ROS 2 node loads all parameters at start up, loads the map as requested by parameters, and publishes the metric map in the corresponding topics. Messages are sent as transient local, so new subscribers can receive them even if they start afterwards.

There are three formats in which maps can be read:

  1. The preferred format is as an mp2p_icp’s metric map file (*.mm), normally generated via sm2mm from a MRPT “simplemap” (*.simplemap) that comes from a SLAM session, e.g. using mola_lidar_odometry.

  2. As a ROS standard YAML file. Here, a *.yaml file specifies the metadata of a 2D occupancy gridmap, which is stored as an accompanying image file. The map will be actually encapsulated into a metric_map_t map with layer name map.

  3. As a serialized MRPT metric map file. A *.metricmap file contains any of the existing MRPT metric maps (point clouds, grid maps, etc.), which may come from custom applications or other SLAM packages. The map will be actually encapsulated into a metric_map_t map with layer name map.

So, whatever is the map source, this node will internally build a metric_map_t with one or more map layers, so it gets published in a uniform way to subscribers.

Refer to example launch files at the end of this file for examples of usage of each of these methods.

ROS Parameters

  • (Option 1 above) mm_file (Default=undefined). Determine the metric_map_t file to load, coming from sm2mm or any other custom user application using mp2p_icp.
  • (Option 2 above) map_yaml_file (Default=undefined): Define this parameter to load a ROS standard YAML file gridmap.
  • (Option 3 above) mrpt_metricmap_file (Default=undefined).
  • frame_id (Default=map): TF frame.
  • pub_mm_topic (Default=mrpt_map). Despite the map source, it will be eventually stored as a mp2p_icp’s metric_map_t (*.mm) structure, then each layer will be published using its layer name as a topic name and with the appropriate type (e.g. PointCloud2, OccupancyGrid,…). Also, the whole metric map is published as a generic serialized object to the topic defined by the parameter pub_mm_topic.

Subscribed topics

None.

Published topics

  • ${pub_mm_topic}/metric_map (Default: mrpt_map/metric_map) (mrpt_msgs::msg::GenericObject) (topic name can be changed with parameter pub_mm_topic).
  • ${pub_mm_topic}/geo_ref (Default: mrpt_map/geo_ref) (mrpt_msgs::msg::GenericObject). An MRPT-serialization of mp2p_icp::metric_map_t::Georeferencing metadata (topic name can be changed with parameter pub_mm_topic).
  • ${pub_mm_topic}/geo_ref_metadata (Default: mrpt_map/geo_ref_metadata)(mrpt_nav_interfaces::msgs::msg::GeoreferencingMetadata). A ROS plain message with the contents of mp2p_icp::metric_map_t::Georeferencing metadata.
  • ${pub_mm_topic}/<LAYER_NAME> (Default: mrpt_map/<LAYER_NAME>) (mrpt_msgs::msg::GenericObject)
  • ${pub_mm_topic}/<LAYER_NAME>_points (sensor_msgs::msg::PointCloud2), one per map layer.
  • ${pub_mm_topic}/<LAYER_NAME>_gridmap (nav_msgs::msg::OccupancyGrid)
  • ${pub_mm_topic}/<LAYER_NAME>_gridmap_metadata (nav_msgs::msg::MapMetaData)
  • (… one per map layer …)

If using options 2 or 3 above, there will be just one layer named map.

Published tf and geo-referenced maps

Refer to the documentation within the MOLA project on geo-referencing for a description of the utm and enu frames, defined by this package if fed with a *.mm file with geo-referenced metadata.

mola_mrpt_ros_geo_referenced_utm_frames

Services

  • GetLayers: Returns the list of map layer names:
# Example usage:
ros2 service call /map_server_node/get_layers  mrpt_nav_interfaces/srv/GetLayers
requester: making request: mrpt_nav_interfaces.srv.GetLayers_Request()

response:
mrpt_nav_interfaces.srv.GetLayers_Response(layers=['map'])

  • GetGridmapLayer: Can be used to request a given map layer of type gridmap.
# Example usage:
ros2 service call /map_server_node/get_grid_layer mrpt_nav_interfaces/srv/GetGridmapLayer "layer_name:\
 'map'"
requester: making request: mrpt_nav_interfaces.srv.GetGridmapLayer_Request(layer_name='map')

response:
mrpt_nav_interfaces.srv.GetGridmapLayer_Response(valid=True, grid=nav_msgs.msg.OccupancyGrid(...

  • GetPointmapLayer: Can be used to request a given map layer of type point cloud.

Template ROS 2 launch files

This package provides launch/mrpt_map_server.launch.py:

ros2 launch mrpt_map_server mrpt_map_server.launch.py

which can be used in user projects to launch the MRPT map server node, by setting these launch arguments:

Demos

Launch a map server from a ROS yaml gridmap (launch file):

ros2 launch mrpt_tutorials demo_map_server_gridmap_from_yaml.launch.py

Launch a map server from a custom .mm map (launch file), which in the launch file is read from the environment variable MM_FILE, so it can be used like:

ros2 launch mrpt_tutorials demo_map_server_from_mm.launch.py mm_file:=/path/to/my/map.mm

  1. The preferred format is as an mp2p_icp’s metric map file (*.mm), normally generated via sm2mm from a MRPT “simplemap” (*.simplemap) that comes from a SLAM session, e.g. using mola_lidar_odometry.

  2. As a ROS standard YAML file. Here, a *.yaml file specifies the metadata of a 2D occupancy gridmap, which is stored as an accompanying image file. The map will be actually encapsulated into a metric_map_t map with layer name map.

  3. As a serialized MRPT metric map file. A *.metricmap file contains any of the existing MRPT metric maps (point clouds, grid maps, etc.), which may come from custom applications or other SLAM packages. The map will be actually encapsulated into a metric_map_t map with layer name map.

So, whatever is the map source, this node will internally build a metric_map_t with one or more map layers, so it gets published in a uniform way to subscribers.

Refer to example launch files at the end of this file for examples of usage of each of these methods.

ROS Parameters

  • (Option 1 above) mm_file (Default=undefined). Determine the metric_map_t file to load, coming from sm2mm or any other custom user application using mp2p_icp.
  • (Option 2 above) map_yaml_file (Default=undefined): Define this parameter to load a ROS standard YAML file gridmap.
  • (Option 3 above) mrpt_metricmap_file (Default=undefined).
  • frame_id (Default=map): TF frame.
  • pub_mm_topic (Default=mrpt_map). Despite the map source, it will be eventually stored as a mp2p_icp’s metric_map_t (*.mm) structure, then each layer will be published using its layer name as a topic name and with the appropriate type (e.g. PointCloud2, OccupancyGrid,…). Also, the whole metric map is published as a generic serialized object to the topic defined by the parameter pub_mm_topic.

Subscribed topics

None.

Published topics

  • ${pub_mm_topic}/metric_map (Default: mrpt_map/metric_map) (mrpt_msgs::msg::GenericObject) (topic name can be changed with parameter pub_mm_topic).
  • ${pub_mm_topic}/geo_ref (Default: mrpt_map/geo_ref) (mrpt_msgs::msg::GenericObject). An MRPT-serialization of mp2p_icp::metric_map_t::Georeferencing metadata (topic name can be changed with parameter pub_mm_topic).
  • ${pub_mm_topic}/geo_ref_metadata (Default: mrpt_map/geo_ref_metadata)(mrpt_nav_interfaces::msgs::msg::GeoreferencingMetadata). A ROS plain message with the contents of mp2p_icp::metric_map_t::Georeferencing metadata.
  • ${pub_mm_topic}/<LAYER_NAME> (Default: mrpt_map/<LAYER_NAME>) (mrpt_msgs::msg::GenericObject)
  • ${pub_mm_topic}/<LAYER_NAME>_points (sensor_msgs::msg::PointCloud2), one per map layer.
  • ${pub_mm_topic}/<LAYER_NAME>_gridmap (nav_msgs::msg::OccupancyGrid)
  • ${pub_mm_topic}/<LAYER_NAME>_gridmap_metadata (nav_msgs::msg::MapMetaData)
  • (… one per map layer …)

If using options 2 or 3 above, there will be just one layer named map.

Published tf and geo-referenced maps

Refer to the documentation within the MOLA project on geo-referencing for a description of the utm and enu frames, defined by this package if fed with a *.mm file with geo-referenced metadata.

Services

  • GetLayers: Returns the list of map layer names:
# Example usage:
ros2 service call /map_server_node/get_layers  mrpt_nav_interfaces/srv/GetLayers
requester: making request: mrpt_nav_interfaces.srv.GetLayers_Request()

response:
mrpt_nav_interfaces.srv.GetLayers_Response(layers=['map'])

  • GetGridmapLayer: Can be used to request a given map layer of type gridmap.
# Example usage:
ros2 service call /map_server_node/get_grid_layer mrpt_nav_interfaces/srv/GetGridmapLayer "layer_name:\
 'map'"
requester: making request: mrpt_nav_interfaces.srv.GetGridmapLayer_Request(layer_name='map')

response:
mrpt_nav_interfaces.srv.GetGridmapLayer_Response(valid=True, grid=nav_msgs.msg.OccupancyGrid(...

  • GetPointmapLayer: Can be used to request a given map layer of type point cloud.

Template ROS 2 launch files

This package provides launch/mrpt_map_server.launch.py:

ros2 launch mrpt_map_server mrpt_map_server.launch.py

which can be used in user projects to launch the MRPT map server node, by setting these launch arguments:

Demos

Launch a map server from a ROS yaml gridmap (launch file):

ros2 launch mrpt_tutorials demo_map_server_gridmap_from_yaml.launch.py

Launch a map server from a custom .mm map (launch file), which in the launch file is read from the environment variable MM_FILE, so it can be used like:

ros2 launch mrpt_tutorials demo_map_server_from_mm.launch.py mm_file:=/path/to/my/map.mm

Overview

This package provides a ROS 2 node that publishes a static map for other nodes to use it. Unlike classic ROS 1 map_server, this node can publish a range of different metric maps, not only occupancy grids.

Node: mrpt_map_server

Working rationale

The C++ ROS 2 node loads all parameters at start up, loads the map as requested by parameters, and publishes the metric map in the corresponding topics. Messages are sent as transient local, so new subscribers can receive them even if they start afterwards.

There are three formats in which maps can be read:

  1. The preferred format is as an mp2p_icp’s metric map file (*.mm), normally generated via sm2mm from a MRPT “simplemap” (*.simplemap) that comes from a SLAM session, e.g. using mola_lidar_odometry.

  2. As a ROS standard YAML file. Here, a *.yaml file specifies the metadata of a 2D occupancy gridmap, which is stored as an accompanying image file. The map will be actually encapsulated into a metric_map_t map with layer name map.

  3. As a serialized MRPT metric map file. A *.metricmap file contains any of the existing MRPT metric maps (point clouds, grid maps, etc.), which may come from custom applications or other SLAM packages. The map will be actually encapsulated into a metric_map_t map with layer name map.

So, whatever is the map source, this node will internally build a metric_map_t with one or more map layers, so it gets published in a uniform way to subscribers.

Refer to example launch files at the end of this file for examples of usage of each of these methods.

ROS Parameters

  • (Option 1 above) mm_file (Default=undefined). Determine the metric_map_t file to load, coming from sm2mm or any other custom user application using mp2p_icp.
  • (Option 2 above) map_yaml_file (Default=undefined): Define this parameter to load a ROS standard YAML file gridmap.
  • (Option 3 above) mrpt_metricmap_file (Default=undefined).
  • frame_id (Default=map): TF frame.
  • pub_mm_topic (Default=mrpt_map). Despite the map source, it will be eventually stored as a mp2p_icp’s metric_map_t (*.mm) structure, then each layer will be published using its layer name as a topic name and with the appropriate type (e.g. PointCloud2, OccupancyGrid,…). Also, the whole metric map is published as a generic serialized object to the topic defined by the parameter pub_mm_topic.

Subscribed topics

None.

Published topics

  • ${pub_mm_topic}/metric_map (Default: mrpt_map/metric_map) (mrpt_msgs::msg::GenericObject) (topic name can be changed with parameter pub_mm_topic).
  • ${pub_mm_topic}/geo_ref (Default: mrpt_map/geo_ref) (mrpt_msgs::msg::GenericObject). An MRPT-serialization of mp2p_icp::metric_map_t::Georeferencing metadata (topic name can be changed with parameter pub_mm_topic).
  • ${pub_mm_topic}/geo_ref_metadata (Default: mrpt_map/geo_ref_metadata)(mrpt_nav_interfaces::msgs::msg::GeoreferencingMetadata). A ROS plain message with the contents of mp2p_icp::metric_map_t::Georeferencing metadata.
  • ${pub_mm_topic}/<LAYER_NAME> (Default: mrpt_map/<LAYER_NAME>) (mrpt_msgs::msg::GenericObject)
  • ${pub_mm_topic}/<LAYER_NAME>_points (sensor_msgs::msg::PointCloud2), one per map layer.
  • ${pub_mm_topic}/<LAYER_NAME>_gridmap (nav_msgs::msg::OccupancyGrid)
  • ${pub_mm_topic}/<LAYER_NAME>_gridmap_metadata (nav_msgs::msg::MapMetaData)
  • (… one per map layer …)

If using options 2 or 3 above, there will be just one layer named map.
