After having some trouble getting visp_auto_tracker to work on groovy, I finally just installed hydro and installed and I was able to track a QR code without any problems!

My main reason for trying out visp_auto_tracker is that, I can tag multiple objects with QR codes and track their poses and attach them to the TF tree so that I can use our robot to move/manipulate the objects. However, when I tried to have two QR codes in the same camera frame, visp_auto_tracker only tracks one of them. When I move one out, it tracks the other.

My question: is there a way to make visp_auto_tracker track multiple QR codes that are in the camera frame at the same time? If not, can anyone suggest of any other package that I can use to achieve what I want do?

I was looking at ar_pose, does anyone know if it is available for ROS Hydro?

If you add the QR-code TF to the main TF tree of the robot, is that mean the robot will be tracking the QR-code once it is detected. For tracking multiple tags, aruco library can do that.
