How to add new fixed obstacles to the map that builded before?

I am really sorry to disturb everyone! And I hope you could forgive me for my poor English!

Now I have a map that builded by a hokuyo laser scanner, and I have a kinect. As the hokuyo could only detect the obstacles in a plane, so the map must miss the obstalces that not belonged to the plane. And now the thing I want to do is to detect these obstacles by the Kinect, and add them to the map that I builded by the hokuyo.

However, I am a newer to the ROS, and I really have no idea for doing this.

And thanks very much!!

if you want to use obstacle which are not in plane you have to use 3d map and navigation. http://wiki.ros.org/3d_navigation

Is that mean that I have no way to add these obstacle to my 2D map?

Sorry for my mindless!! The obstacles I want to add are, uh, some fixed obstacles that lower or higher than the hokuyo laser scanner, they cannot be detected by the laser scaner, but they are there and they are fixed! So I want to add them to the map...

I guess one of the obstacle can be table surface which cannt be seen by laser. I don't know any method todo it in 2d.
