Hi ros user!

I try to use a Asus Xtion pro live with ROs Fuerte and openni_launch. I have made a lot of test but I have not been able to make it work. It is always the same thing I have got this Error message :

[ERROR] [1337435292.200305197]: Tried to advertise a service that is already advertised in this node [/camera/depth_registered/image_rect_raw/compressed/set_parameters]

[ERROR] [1337435292.210206934]: Tried to advertise a service that is already advertised in this node [/camera/depth_registered/image_rect_raw/theora/set_parameters]

Exept this error every thing else seems alright. It detect the camera :

[ INFO] [1337435291.552393164]: Number devices connected: 1
[ INFO] [1337435291.552631121]: 1. device on bus 001:03 is a PrimeSense Device (600) from PrimeSense (1d27) with serial id ''
[ INFO] [1337435291.554548510]: Searching for device with index = 1
[ INFO] [1337435291.687868149]: Opened 'PrimeSense Device' on bus 1:3 with serial number ''

But there is no message publish on the topic /camera/depth/points. I have tried different topics but none of then publish any message. I use RVIZ to see the topics.

I was previously running ros on Ubuntu 10.04 running on VMWare Player. When I encourtered this error I decided to try on different Ubuntu version but I have got the same error on each of the version I have tried.

I have tried Ubuntu 11.04, 11.10 and 12.04. On ubuntu 12.04 I have got much more error so I concentred myself on ubuntu 11.10 which I suppose is the better version of Ubuntu to work with Asus Xtion. I have even try to install ros fuerte from source but it doesn't resolve anything. Still the same error!

Now I don't know what to do. Have I missed something?

I guess that with ros fuerte and openni_launch I have nothing else to install? right? Openni Driver and everything else is package with openni_launch? right?

Any help apreciate.

Things in advance.

Regards.

Christophe.

EDIT TO MY INITIAL POST:

Yes all my previous try where done on VMWare. I have now installed Ubuntu 12.04 directly on my PC and now everything works fine! I am able to see point cloud in RVIZ! Thanks for taking time to answer me!

Those messages are normal when running the openni launch file.

There are at least two possibilities here:

  • You haven't chosen an appropriate frame in rviz
  • Your driver isn't publishing any messages

You can troubleshoot the point cloud topic without rviz by doing

rostopic hz /camera/depth/points

If you don't see any output within 30 seconds or so, there's a problem with your driver. If you see output indicating that the driver is publishing around 30Hz, the problem is with your rviz settings.
