Tf frequency is too large
Is this frequency of tf between /base_link
and /laser
normal? It is 10000HZ!!!

@gvdhoorn is right. Static transforms go through a separate mechanism and the 10000 Hz is a shorthand way/placeholder to display the information in the same context.
You can see the buffer length is also 0.0 and the most recent transform will get quite old, but it's accurate. An enhancement could be made to the tool to display the static transforms separately with a dedicated display type.

Correct way to publish a 3D PointStamped target for head tracking?
The most common frequency of publishing TF is 100Hz
It's probably a static transform, meaning it doesn't really have an update period. The
rate
shown there is (but I'm speculating a bit here) just an indication of 'very fast' or 'instantaneous'.I'm not sure that is really something that can be so generally stated. It's completely up to the application.
Then let me rephrase it. In my experience the most common frequency of static TF publishing is 100Hz. :)
Thank you two friends! I got this.
