fiducial_slam ignores fiducial_id 0 #199

Closed rcywongaa closed 4 years ago

rcywongaa commented 4 years ago

It seems fiducial markers with id 0 are actively ignored in the mapping process. No blue line is drawn between existing markers and marker id 0, and /fiducial_map does not publish fiducial_id: 0

Replacing marker 0 with any other marker fixes the issue.

Fiducial id 0 had a special meaning in the past. In the kinetic-devel branch on github this meaning has been removed, so if you build from source it should work as expected.

Thanks for the clarification!
