aruco_mapping not working

[SubMishMar]

I am trying to localize a simple USB camera using aruco markers sized 0.141 m. I am using ROS kinetic. My plumbing is complete and the remappings are correct. I am even able to get the video feed (mono 8) but I am unable to understand why the detection+pose estimation part is not working at all.

I am providing the link to the repository I have forked so that my scenario can be easily reproduced. Here is the github link: https://github.com/SubMishMar/aruco_mapping

In order to reproduce it I have also recorded a bag file which can be downloaded from the link provided in the folder named aruco_mapping_bag inside the provided repository.

The launch file that should be used is aruco_usbcam.launch. After running this launch file. run the bag file and one can see that the detection doesn't work (at least for me).

I will be glad if someone can help me here! I have been trying to fix this for a long time.

I got this figured out. I was using the wrong aruco marker (i.e. the dictionary didn't match). But now I wonder where can I set the dictionary type?

Hi @SubMishMar which Aruco marker did you use, I'm having the same problem detecting the markers

Use this http://chev.me/arucogen/ and choose the Original Aruco dictionary.

How can we know which dictionary we use in the aruco_mapping package?
