Hello,

i hope someone could help with ardrone tag recognition. I am subscribing ardrone/navdata in my code and i receive all values except for the tag detection values, which are always 0 or empty. When i echo this topic from my terminal it seems as if my drone is not recognizing them at all. I have these orange/green stripes as tags and an ardrone 2.0. Do i need to calibrate the camera or something like this? (I am using ardrone_autonomy)

I'd be glad if someone could help me! (And sorry for my english ;))

(Oh i have marked this post as a wiki.. how do i delete this? XD)

I hope we can get an answer for this problem. I am also having the same problem. All the parameters for tag detection seems correct. The drone detects tags on iphone app. But not on ROS. Also tried the ready package available on robohub but no chance. Detected tag number and tag positions are always 0 never updated.
