[ros-users] uvc_camera and stereo_proc

This is the example of the output i get from different packages:
If gscam package using single camera:


If i use usb_cam package then i get (Single camera),

I can use any of the above packages in image_proc
ROS_NAMESPACE=my_camera rosrun image_proc image_proc
$ rosrun image_view image_view image:=my_camera/image_rect_color
Here i replace my_camera with either /usb_cam or /gscam


If i use uvc_stereo package i should expected to get,
(same for right side camera)

Instead, i get directly, (W/o /uvc_stereo)
(same for right side camera)

This is hard to replace in the image_proc_stereo package like above case.
As per package it should expect,
$ ROS_NAMESPACE=stereo rosrun stereo_image_proc stereo_image_proc
$ rosrun image_view stereo_view stereo:=/stereo image:=image_rect_color

But, here i dont get either /stereo OR /uvc_camera to replace /stereo since
i get /left/image_raw topic and not /<stereo>OR</uvc_camera>/left/image_raw

Do you suggest any way to get such publish topics through uvc_stereo package
so as to use it in image_proc_stereo?
I hope it is not confusing. :-) I have tried my best to explain it. Please
let me know if it is still not clear.
