For your target frame to be odom, there must be a valid set of transforms between the velodyne's frame (by default, velodyne) and the odom frame. Is this true for your setup?

how can i set odom to velodyne frame? when i use this driver, should i make odom to velodyne tf?

[jaeseok4104]

I didn't understand what you said. I think this driver posts point cloud in velodyne frames, and I think if I set to velodyne frames in rviz, I should be able to see point cloud data.

when i use ros-noetic i could used this driver. don't surrport melodic version?

If you want to use an /odom frame then yes, you need to publish a TF between /velodyne (the default frame for the sensor) and /odom. If you do not want to use /odom then you can just change rviz to view in /velodyne frame.

melodic was supported until 2 weeks ago when melodic became end-of-life. The driver was confirmed to work on melodic by many users for a very long time. If you still want to use melodic, you can use the melodic-devel branch of this repository or the apt package.
