I am using ubuntu 11.10.

I place the kinect toward white wall

and

rosrun image_view image_view image:=/camera/depth/image

I can see the depth image

But rostopic echo /camera/detph/image

put different numbers(datas).

How can I get the same datas?

And how can I find actual distance using openni driver?

What do you mean different? Are they very different, then something is wrong. If they are just a bit different, then that's normal. It's a sensor that has noise.

For the distances, you would subscribe to a pointcloud2 topic and not the depth image.
