I have been trying to use fast plane detection(http://www.ros.org/wiki/fast_plane_detection) with Kinect disparity map data. This package expects cameraInfo to be available to detect the dominant planes. But I have not been able to get the camerainfo from the kinect. Though rostopic list shows the presence of topics /camera/rgb/camerainfo and /camera/depth/camerainfo , these topics remain empty.

rostopic echo /camera/depth/camerainfo and also /camera/rgb/camerainfo donot give any information.

Is there any reason these topics are Null and is there a way to get these topics to the package ?

PS: I have been using Openni kinect package to interface kinect and i am able to visualize kinect 2d/3d data in rviz.

I was having the same problem. Check this thread to see if it matches what you're seeing. It fixed the problem for me.

Tried updating to the latest version as suggested in the link. doesnot seem to solve the issue. l have been trying to publish a camera_info message separately to see if it works.
