IR kinect subscribtion

edit

Hi there.

I'm working with the Kinect in ROS. Had anyone subscribed to /camera/ir/image_raw ? because I get black screen when I launch this command in the shell:

$> rosrun image_view image_view image:=/camera/ir/image_raw

and how to subscribe to it using c++ program like that : what should I put instead of mono8 ? (Raw uint16 IR image data is given by the topic)

void imageCallbackir(const sensor_msgs::ImageConstPtr& msg)
{   
    cv_bridge::CvImagePtr cv_ptr;

    try
    {
        cv_ptr = cv_bridge::toCvCopy(msg, sensor_msgs::image_encodings::MONO8);

    }

    catch (cv_bridge::Exception& e)
    {
        ROS_ERROR("cv_bridge exception: %s", e.what());
        return;
    }


    cv::imshow("OpenCV viewer Kinect ir", cv_ptr->image);

    cvWaitKey(3);
}

Thank you.
