ERROR run with Rslidar

[RuPingCen]

Hi, @rsasaki0109 . I encountered a problem where when I use rslidar for localization, the trajectory is not displayed in RVIZ, and even when I print the topic "/path", there is no output. This point cloud map was built using lidarslam_ros2.

Befor run pcl_localization_ros2 node, I change the yaml file

/**:
    ros__parameters:
      registration_method: "NDT_OMP"
      score_threshold: 2.0

      enable_debug: true

Also, I hace change the point cloud input topic and lidar_tf for the launch file

    ld.add_action(pcl_localization)
    ld.add_action(lidar_tf)

    return ld

Here is the commands for launch pcl_localization_ros2 node

ros2 launch pcl_localization_ros2 pcl_localization.launch.py
rviz2 -d src/lidar_localization_ros2-0.2.0-humble/rviz/localization.rviz

Then, play the bags

ros2 bag play rslidar32_xsens_1

the terminator output information:

The Rviz can successfully display the map, but cannot display real-time input point clouds and path.

I wonder why the algorithm does not output a positioning trajectory, and does it not support the use of other lidar?

[rsasaki0109]

I think it should work with Rslidar as well. Wouldn’t the issue be resolved by adding the --clock option when using ros2 bag play?
