This node uses camera_info_manager for dealing with camera_info. If no calibration data is set, it has dummy values except for width and height.

 * ~rate (double: default 30.0) publish rate [Hz].
 * ~device_id (int: default 0) capture device id.
 * ~frame_id (string: default "camera") frame_id of message header.
 * ~image_width (int) try to set capture image width.

 * ~camera_info_url (string) url of camera info yaml.
 * ~file (string: default "") if not "" then use movie file instead of device.

{{{
rosparam set cv_camera/device_id 0
rosrun cv_camera cv_camera_node
}}}


 * with the first line set the camera device to use
 * run the node with the second line
