Hi Reza,

did you check the box "All topics" in rxgraph. With that option you should get an overview of all topics which are available. Maybe you launched the nodes in different namespaces? While creating your own launch files, YOU have to make sure that the topics are connected correctly.

Regards,
Florian

Betreff: Re: [ros-users] uvc_camera and stereo_proc

Hi, 
I have same problem with prosilica cameras on care-o-bot. It's supposed that either image_proc and stereo_image_proc are subscribed into camera nodes, but neither image_proc nor stereo_image_proc subscribe into camera nodes. I checked them by rxgraph and rosnode info. 

Reza,

Hello Eric, 

 I have run 
roslaunch uvc_camera stereo_node.launch
then,
rosrun stereo_image_proc stereo_image_proc __name:=proc 

then, rxgraph gives,

/uvc_camera_stereo and /proc are independently connected to the /rosout but
no connection in between them.

I have calibrated both the cameras.
