If you iterate over the pointcloud, you can get all the coordinates. The question needs more clarity.

I need to extract the coordinates of each point so that I can see the coordinates of each point in real time. Rvzi doesn't seem to show the coordinates of each point in real time.What should I do to iterateover the pointcloud?

Rviz displays the pointcloud data if you subscribe to the topic and in the correct frame. To extract the coordinates of all the points as [x,y,z], you will have to iterate over the pointcloud.

The millimeter wave radar sensor I use is IWR1642BOOST. I'm sorry I'm not familiar with rvzi now. Could you tell me your email address? I would like to send you more details, such as my rviz interface.
