Good to hear the progress!
When you run rostopic list do you see the /camera/color/image_new topic listed?
When you run rostopic hz /camera/color/image_new does it show that this topic is receiving data? (should be around 10 Hz)
I’ve also done this before… the track_aruco.py script must be running in order for there to be data to be published to image_new. The image_new topic could appear as a grayed out blob if the track_aruco.py script isn’t running
If not, would you mind emailing me your file so I could directly help with debugging?
Thanks!
