Hi, Is there any progress on this issue. Does the cartographer now support landmarks without unique IDs? Are markers without orientation now supported, e.g. reflectors.

I only modified rbpf_slam

Very good point! Three ideas: 1. We thought it would be good to add sigma values to the Detector message for spherical coordinates but that would mean that all marker...

Hi using `angle_{horizontal|vertical}_{min|max}` has the benefit to define a field of view and of course one hast to be careful not to go beyond `2pi`. The information is needed if...

you are right it is not that simple without additional agreements. instead of `angle_{horizontal|vertical}_{min|max}` we could add a could add a quaternion for the view direction and two variables to...

We made a implementations using the MarkerDetection messages for `stage_ros` publishing fiducials. https://github.com/ros-simulation/stage_ros/pull/36 and soon we like to publish a node for doing slam using fiducial messages form stage and...

I know there are other similar message out there but that's exactly a issue why I like to proposed a set of marker messages. `ar_track_alvar_msgs` are not supporting sensor parameters...

What about that, I will make a new pkg `marker_msg` with the proposed messages types. In addition we will offer a pkgs to view the marker in rviz `marker_rviz_plugin`, a...

A `type` field is a good idea but the name under which the message is published can serve as identifier for the type unless you like to mix in one...
