rostopic echo /aruco_simple/pose not working
Closed this issue · 3 comments
Config: ROS 1, Melodic, Ubuntu 18.04
Hi,
I am trying to track 2 markers with the double.launch file. The 2 markers are detected and I can see the result using image_view node in the usb_cam pkg. However, when I echo the pose and pose2 topics they are blank.
I can echo the /tf topic and see the hand and object frames being published. Please let me know if you need additional info!

Hello @Sun-Jing-Kang and @Abhinavgandhi09
Thank you for your interest in the aruco_ros
library. Regarding your issue, the aruco_ros single only publishes the info of the marker and its pose only for the matching marker ID. The one you see in the image are all the detected ArUcos, but if the detected ArUco marker is of not the intended one, it doesn't publish the info.
For instance, as below you might detect 100s of ArUcos but you might be interested in a specific one. You would need to specify the marker_id while launching the launch file with the argument: markerId:=582
We hope this solves your issue.
Thank you,
Best Regards,
