hector_qrcode_detection

edit

I can't to start work with hector_qrcode_detection. I edited this launch file I only change this sector

<remap from="openni/image"             to="/image_raw" />
<remap from="openni/image_percept"     to="worldmodel/image_percept" />
<remap from="openni/image/qrcode"      to="image/qrcode" />
<remap from="openni/image/camera_info" to="/camera_info" />

Because I use uvc_camera for testing, but I going to use this package with kinect. So when I start this launch file, I didn't see that any topic supsribes to image_raw. Where is problem? What I'm doing wrong?
