Description
Steps to reproduce:
Publish Image and CameraInfo using CameraPublisher.
Observed & Expected:
Image frame rate (as measured by ros2 topic hz) is around 8. Expected: equal to the CameraInfo frame rate.
CameraInfo frame rate (as measured by ros2 topic hz) is around 16. Expected: equal to the Image frame rate.
Questions:
Could it be that any other Image fails to be published?
Could it be an issue with ros2 topic hz?
