No result shows

Hello ！After running the example program, I'm not seeing any visualization results in RViz. It says the specified coordinate frame doesn't exist. Are there any parameters that need adjustment? I converted a ROS1 bag file to a ROS2 bag file for playback

looks like something is wrong with your tf

what are the output of these?

ros2 run rqt_tf_tree rqt_tf_tree

ros2 topic echo --once /points --field header

The default point-topic is nonground. but in the bag there is no message called nonground. And in the code, I also can't see the publisher which will send nonground.

@zjuyy113 In the readme there is describing how start with subscribing to /my_custom_cloud_topic:

ros2 launch pointcloud_to_grid demo.launch.py topic:=my_custom_cloud_topic

Instead of /my_custom_cloud_topic use any pointcloud topic
