[BUG]: Framerate of gazebo camera is 1Hz

[marc-hanheide]

Description of the bug

The framerate is 1Hz only!

I'm surprised by this comment:

limo_ros2/src/limo_description/urdf/limo_gazebo.gazebo

Lines 91 to 93 in 10a964a

	<!-- Keep this zero, update_rate in the parent <sensor> tag
	will control the frame rate. -->
	<updateRate>0.0</updateRate>

This does not appear to be working. Any of you @LeonardoGuevara, @jondave , @pulver22 encountered this as well?

Steps To Reproduce

run simulation and run ros2 topic hz /limo/depth_camera_link/image_raw

Additional Information

No response

I assume from the comment it takes the frame rate from the <sensor> tag above this where the rate is 30 Hz <update_rate>30.0</update_rate>?

limo_ros2/src/limo_description/urdf/limo_gazebo.gazebo

Line 74 in 10a964a

<update_rate>30.0</update_rate>

Well... that appears to be the theory. But the frequency I measure is 1Hz (or rather 0.9997 Hz to be precise). Is it 30 for you?

[LeonardoGuevara]

I also encounter that issue. For some reason when I run ">> ros2 topic hz /limo/depth_camera_link/image_raw" nothing is printed, but I can see the image is being published in rviz, and also can see that the messages are received more or less every second (~1Hz). I am not using GPU image, could be that the reason?

[marc-hanheide]

no,. nothing to do with GPU. If you check the Ros parameter you seem it's set to 1Hz and when I set it to 30.it publishes at 30. Just a configuration issue.
