Launch the node

Launch the camera node (assuming you are in ~/colcon_ws/):

$ . install/setup.bash
$ ros2 launch ifm3d_ros2 camera.launch.py

This will launch a /ifm3d/camera/ node with default arguments, i.e. utilize the defaults yml configuration camera_default_parameters.yaml.

The respective node information should look like this: ros2 node info /ifm3d/camera

/ifm3d/camera

Note

We also provide a helper launch file to start multiple camera nodes. See the documentation here.

To visualize the data with RViz, set the visualization argument of the launch script to true:

$ ros2 launch ifm3d_ros2 camera.launch.py visualization:=true

Congratulations! You can now have complete control over the O3R perception platform from inside ROS2.
