Ros2 Foxy resize node, cannot find published camera_info

Open lancevoly opened this issue 4 years ago • 1 comments

I am using the resize node in ros2 foxy, which subscribes from a camera_info topic and republishes it with updated camera_info. I wonder how I can subscribe to the updated camera_info, which is denoted as ~camera_info in the ros wiki. I tried node_name/camera_info, but it doesn't work.

Thanks for the help!

In my tests ResizeNode subscribes and publishes to the same camera info topic, so the original and modified CameraInfo messages are mixed. This basically makes ResizeNode unusable.

I think this is the root cause: https://github.com/ros-perception/image_common/issues/187

Appears that #693 is the workaround for this, there are other tickets following image_transport issues.
