Error while running ros image_pipeline camera calibration
I am following the following link to get image_pipeline running:
http://wiki.ros.org/camera_calibratio...
I have a stereo camera setup
I am running usb_cam to generate the following topics and services as required by image_pipeline:

I am running the following command to calibrate: rosrun camera_calibration cameracalibrator.py --approximate=0.01 --size 8x6 --square 0.108 right:=stereo/right/image_raw left:=/stereo/left/image_raw right_camera:=/stereo/right left_camera:=/stereo/left
And I am getting the following error:

Waiting for service /stereo/left/set_camera_info ...
OK
Waiting for service /stereo/right/set_camera_info ...
OK
