I don't get any data (rgb image,depth image,rviz) from the kinect,I'm running on Ubuntu 10.10 ,diamondback;basically what I did is :

1) I set up my computer to accept software from ROS.org

2) I ran roscore on a new terminal by typing : roscore

3)I installed openNI kinect by typing : sudo apt-get install ros-diamondback-openni-kinect

4)I installed openNi camera by typing : rosmake openni_camera

5)I launched the openNI driver by typing :roslaunch openni_camera openni_node.launch

6)I ran rviz by typing: rosrun rviz rviz

7)I ran the rgb camera by typing : rosrun image_view image_view image:=/camera/rgb/image_color

please help me fix it.

Where did you get these instructions from? These are not the standard wa to install the kinect drivers.

If you would like to view images coming from the kinect camera, follow the instructions posted here: http://www.ros.org/wiki/openni_kinect and here: http://www.ros.org/wiki/openni_camera

which are summarized as follows:

install openni_kinect: sudo apt-get install ros-electric-openni-kinect
run openni: roslaunch openni_launch openni.launch
run image viewer: rosrun image_view image_view image:=/camera/rgb/image_color

@bassim do you see any errors in the terminal when you roslaunch openni_camera openni_node.launch .. can you rostopic hz /camera/rgb/image_color

mmwise ( 2011-11-04 06:56:11 -0500 )edit

when I typed on a new terminal : rostopic hz/camera/rgb/image_color . I got this : WARNING: topic [/camera/rgb/image_color] does not appear to be published yet

bassim ( 2011-11-04 07:42:13 -0500 )edit

are there any errors in the terminal where you called roslaunch openni_camera openni_node.launch?

mmwise ( 2011-11-04 16:32:57 -0500 )edit

no , I didnt get any error !

bassim ( 2011-11-07 01:41:04 -0500 )edit

can you copy and paste the output from that terminal into your question

mmwise ( 2011-11-07 10:11:40 -0500 )edit

you should see a line like this in the output ... [ INFO] [1320711146.846538470]: Number devices connected: 1

First, pasting half of the web into your question doesn't help.

What's this KinectROSPackage thing you're talking about? You should just install openni_kinect from the binaries:

sudo apt-get install ros-electric-openni-kinect

and then use the various nodes it provides.

Do you see the IR-Laser of the Kinect actually turning on when you subscribe to any of the depth-related topics?
