[ros-users] ar_pose with USB camera

[Steven Bellens]

Hey,

I had this set-up working before, but can't remember what I did
different. Either I'm missing something or one of the packages has
changed.
>From the ar_pose wiki:

"Currently the ar_pose package requires calibration information from a
camera_info topic. If there is no camera_info topic the marker pose
estimation will not start."

Further on the option is given to try the package with the usb_cam
driver: http://www.ros.org/wiki/usb_cam

Which however, does not publish a camera_info topic.

How can I make this work?

best regards,

Steven
