Abhy, You could remap the namespace as what Raphael said. In your stereo_node.launch insert this inside the camera node: . 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?).
