2020-01-13 04:38:20 -0500	marked best answer	How to read markers in ar_track_alvar? Hi there, I was trying to use this pkg ar_track_alvar to detect a tag, and I found out that it keeps recognizing random things as tags.

Does anyone have any idea about it? Thank you in advance! Best Regards Updates if I add code on, the tag looks like this in simulation about false positive: when the camera is heading to a wall with 3 gray patches(without any code on them) and this is what the topic /ARmarker_points shows
