Detecting markers of different sizes simultaneously

[elstongunnn41]

I am using an aerial vehicle that has a bottom camera (no kinect) and I am using it to detect an ARTag. It works perfect when it is only one, but now I need to add some more tags so they can be seen at different heights. I read that some people did that but I didn't find how, because I would like to define the sizes of all the possible markers but I can only define one.

What can I do? Use more than one pr2_indiv_no_kinect.launch file? My tags would be something like:

@elstongunnn41 Could you solve that issue? I have that same problem.
