Abhy,
IIRC, the stereo image proc node doesn't need to be pushed down into a namespace. That is only important if you are running multiple pairs of cameras.
What is the output of rxgraph if you run uvc_stereo and stereo_image_proc, both with no remappings or namespaces? Does stereo image proc successfully subscribe to your cameras and output point clouds/disparity images?

Hi,
This is the example of the output i get from different packages:
If gscam package using single camera:
/gscam/image_raw
/gscam/.....
If i use usb_cam package then i get (Single camera),
/usb_cam/image_raw
/usb_cam/.....
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
Now,
If i use uvc_stereo package i should expected to get,
/uvc_stereo/left/image_raw
/uvc_stereo/left/......
(same for right side camera)
Instead, i get directly, (W/o /uvc_stereo)
/left/image_raw
/left/......
(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,
/stereo/left/image_raw
/stereo/left/camera_info
/stereo/right/image_raw
/stereo/right/camera_info
$ ROS_NAMESPACE=stereo rosrun stereo_image_proc stereo_image_proc
__name:=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.
