`MapServer`	MapServer component used for reading and converting map data from file to serve a global map. Supports both 2D maps with a YAML file and 3D maps with PCD files.

API¶

class kompass.components.map_server.MapServerConfig¶

Bases: kompass.config.ComponentConfig

MapServer component configuration parameters

Name	Type, Default	Description
map_file_read_rate	`float`, `0.0`	Rate to read and convert the map data from file. If zero, converts once.
pc_publish_row	`bool`, `True`	Publish the row point cloud data read from the file. Only applicable if input is `.pcd` file.
pc_frame	`Optional[str]`, `None`	Frame ID to use when publishing the point cloud data. If `None`, uses the world frame.
map_file_path	`Optional[str]`, `None`	Path to the map file.
custom_map_frame	`Optional[str]`, `None`	Custom frame ID for the map.
grid_resolution	`float`, `0.05`	Resolution of the occupancy grid if generating from point cloud.
z_ground_limit	`float`, `0.01`	Points below this height value are considered ground. Used only for point cloud input.

class kompass.components.map_server.MapServer(component_name: str, config_file: Optional[str] = None, config: Optional[kompass.components.map_server.MapServerConfig] = None, outputs: Optional[Dict[str, kompass.components.ros.Topic]] = None, **kwargs)¶

Bases: kompass.components.component.Component

MapServer component used for reading and converting map data from file to serve a global map. Supports both 2D maps with a YAML file and 3D maps with PCD files.

Outputs:

Key Name	Allowed Types	Number	Default
global_map	`nav_msgs.msg.OccupancyGrid`	1	`Topic(name="/map", msg_type="OccupancyGrid")` - Global map generated from input data.
spatial_sensor	`sensor_msgs.msg.PointCloud2`	1, optional	`Topic(name="/row_point_cloud", msg_type="PointCloud2")` - Row point cloud data for visualization or further processing.

Available Services:

Save2dMapToFile: Saves the 2D map to a file (YAML format).
Save3dMapToFile: Saves the 3D map to a file (PCD format).

Usage Example:

from kompass.components import MapServerConfig, MapServer
from kompass.ros import Topic

# Setup custom configuration
my_config = MapServerConfig(
        map_file_read_rate=5.0,
        map_file_path="/path/to/your/map.pcd",
        grid_resolution=0.1,
        pc_publish_row=False,
    )

# Init a MapServer object
my_map_server = MapServer(component_name="map_server", config=my_config)

init_variables()¶: Overwrites the init variables method called at Node init

create_all_timers()¶: Create all node timers

create_all_services()¶: Creates all node services

destroy_all_timers()¶: Destroys all node timers

destroy_all_services()¶: Destroys all node services

convert_map_from_file() → bool¶: Convert the map from file to OccupancyGrid message
