Hi, I try to use aruco_ros in melodic. pal-robotics A few basic questions came up:

-does aruco_ros already include a filter of some sort (outlier detection) or does it output raw data? -Is there a topic/service or other clues as to know if a marker was detected at all? -Where is the actual library (for print), I found the folder

arucomip36h12_pdf

including marker pdfs but they dont seem to be the ones used in the pal-robotics examples. -Is there any good documentation or tutorials out there, specially the mentioned feature:

Enhanced precision tracking by using

Any help would be appreciated.
