EDIT

Hello I am using Logitech camera by using usb_camera usb_camera.launch file witgh Package brownrosusbpkg for Rosindigo system.I checked with /devVideo 0 or 1,The Error still there.

<launch>
    <node name="usb_cam" pkg="usb_cam" type="usb_cam_node" output="screen" >
        <param="" name="video_device" value="/dev/video1"/>
    </node>
</launch>

But I get error in Camera Calibration Waiting for service', '//setcamerainfo,Service not found.

and now in visualizing the Artagsalvar.I sucessfully build alvar and using ROS_indigo packages.
