Multimarker tracking using ar_pose

asked 2016-06-29 03:10:24 -0500

Hi, I'm a newcomer to ROS and I'm trying to track an object using ar_pose. I'm able to track several markers at the same time but I don't know how to track an object with several markers like the picture below. image description I understand the marker.dat file in the data folder but I don't know how to use it and the demos seems to be broken. Does somebody have a solution ?

I would recommend to use ar_track_alvar instead. It is able to track marker bundles with findMarkerBundles node. A bundle is a set of markers belonging to the same rigid body, like the cube on your photo. The library will always return a pose of the first marker in the bundle, no matter what markers from the bundle are actually visible to the camera.

(Kinetic documentation tab is broken on ROS Wiki, so choose Jade or Indigo tab)
