Abhy,

You could remap the namespace as what Raphael said. In your stereo_node.launch insert this inside the camera node: <remap from="left/image_raw" to="/stereo/left/image_raw" />. Do this with the right as well, then you could use the $ROS_NAMESPACE=stereo rosrun stereo_image_proc stereo_image_proc __name:=proc.

You could also try this one: $ROS_NAMESPACE=/ rosrun stereo_image_proc stereo_image_proc __name:=proc. When you got this topic "/left/image_raw" your namespace becomes "/"(am i right on this?). I think I've encountered this one already.

Look at this: http://www.ros.org/wiki/Names

Hi,

Yes, i have already checked with "All topics", the result

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

stereo_proc and uvc_camera are working independently. They are only
connected to rosout.

Am i missing something by any chance?
