not sure if I should open a new topic for this, but it looks like the
ar_pose package is not functioning properly anymore. Attached is a
screenshot I get (tested on multiple computers) when running the demo
launch file demo_multi.launch with the provided bag file. The tracking
process completely mis-estimates the marker position as you can see.
I've looked into the git history to try to find any recent changes
which can explain this, but I haven't found anything useful.
Do others see the same behaviour?
Did the package recently undergo any changes which might cause this?
