Currently you can't, as we have not released our packages used for QR code detection yet. The underlying semantic worldmodel is released however, see the hector_object_tracker package. More detailed documentation is in the works, but will not be available till after RoboCup due to time constraints.

The hector_qrcode_detection package which we also use for RoboCup is available in the hector_vision stack now: https://github.com/tu-darmstadt-ros-pkg/hector_vision .

Thank you stefan,

after detecting Qrcodes i need to mark objects in map by hector_object_tracker. i have added object_tracker in my launch file, and i am using your rqt_rescue plugin in this address: irrw2012/source/browse/trunk/rqt_rescue_control_plugin/lib/RescueControlDialog.py#59

but when i click on "Add victim in front of robot" button, in running launch file terminal, it prints this line:

[ INFO] [1370900109.430975931]: add_object service called for new victim object in frame base_link

and in rqt termianl it prints:

service call failed

and after saving maps, no mark added to the map. what should i do in this situation?

@stefan Can you share the documentation regarding the hector_qrcode_detection.I am not able to do the remap from the /image or /image_raw. No data is being published in that node and also there is no topic running in it.Can u help me for sorting this out. Thanks in advance.
