Verify camera topics
Check that the camera node is streaming images and at the expected frame rate.
After launching the camera driver you should verify that images are being published at a reasonable rate. The commands below display images and measure the frequency of the /camera/image_raw topic.
bash
ros2 topic echo /${ROS_NAME}/camera/image_raw
bash
ros2 topic hz /${ROS_NAME}/camera/image_raw
bash
ros2 topic list
