Configuration Overview

By default, the SLAMcore software comes preconfigured and fully functional with its default algorithm configuration. However, users may use configuration files to adjust the settings based on test conditions (e.g. a large room or outdoors) to potentially improve performance in that particular environment.

We provide a set of presets configured for the most common use cases, which users may further tweak to suit their needs.


The SLAM configuration files are only compatible with SLAMcore Software Version 21.01 and above, and the mapping configuration files with Version 21.03 and above.


The configuration files are downloaded along with the “SLAMcore Tools” packages for Ubuntu 18.04 (x64) and NVIDIA Jetson platforms at the SLAMcore Portal, and installed under the /usr/share/slamcore/presets directory.


Users of the ROS Wrappers will be required to download and install the non-ROS packages to obtain the preset files.



Providing a configuration file is optional: the algorithm falls back to appropriate defaults if one is not provided.

Visualiser, Dataset Recorder and CLI

Specify a configuration file for slamcore_visualiser and slamcore_dataset_processor by using the -c or --config flag, for example:

$ slamcore_visualiser -c /usr/share/slamcore/presets/high_accuracy.json

ROS1 Wrapper

Specify a configuration file for the SLAM ROS1 node by using the config_file parameter of the run_slam.launch file, for example:

$ roslaunch slamcore_slam run_slam.launch config_file:=/usr/share/slamcore/presets/high_accuracy.json

Alternatively and in case you are not using our provided launchfile, you can write the configuration file path to the /slamcore/config_file ROS1 parameter directly and then run the slam_publisher node:

# Make sure to set the parameter *before* running the node
$ rosparam set /slamcore/config_file "<path/to/config/file>"
$ rosrun slamcore_slam slam_publisher

ROS2 Wrapper

Specify a configuration file for the SLAM ROS2 node by using the config_file parameter of the file, for example:

$ ros2 launch slamcore_slam config_file:=/usr/share/slamcore/presets/high_accuracy.json

Configuration File


The presets contain parameters tuned to the most common use cases:


Target Use Case


Office environments with a hand-held camera


High accuracy with no constraints on computation time


Wheeled robot moving on one dominant ground plane


Running on low performance hardware


Outdoor robot/drone use with landmarks far from the camera


Indoor robot navigation use with landmarks far from the camera


Height/occupancy map generation example


Some of the preset settings can significantly change the processing times.

It is recommended to use high_accuracy.json on prerecorded datasets to generate a high quality map offline, and then use a less computationally expensive configuration for live localisation.

Custom Configuration

Each configuration file is a collection of settings in .json format used for the SLAM algorithm. Users may create their own configuration files based on the presets we ship.

The following two pages describe the common configuration parameters for tuning:
