I’m using the Aruco/Opentrack system too, for some time now and am happy with it. I use it with a cheap webcam. Works very smooth if you configure it right.
A 2nd big advantage i.m.h.o. is that it uses almost no CPU. I tried it with AITrack, but my CPU temp went sky high.
And yes, it looks odd with that thing on your cap, but if nobody can’t see, who cares…
