Installation problem with kinect

Hello. I am new to ROS/Ubuntu and hoping someone could shed some light into my problem.

My main problem is that I cannot see any result of depth and RGB from Kinect, even though I installed following instructions introduced from http://www.ros.org/wiki/kinect.

Below is what I have done so far:

  1. I have installed openni_kinect (electric); "sudo apt-get install ros-electric-openni-kinect "
  2. unplug and plug in the Kinect.
  3. type command "roslaunch openni_launch openni.launch."

    ** result image shown:link image

    As you can see from the image description, it seems the above command has registered kinetic

  4. when I run "rosrun rviz rviz", it does not show anything except black screen so far. Is there anything specific I should be doing to RVIZ to get the kinetic camera to capture?

Thanks for you help.

Thank you so much. I did as you mentioned. It worked. I really appreciate that. I have another question. RVIZ screen shows only black and white colors. Is there any way to get RGB with depth and how can I see 3D pictures. Thanks.

You need to subscribe the appropriate topic. One is named rgb one depth iirc. Also select color transformer RGB8.
