I use ubuntu 12.04 with fuerte.

I followed rgbdslam.

When I run rgbdslam,it shows the error:

  sam@sam:/media/Data/code/ros/slam/rgbdslam$ roslaunch rgbdslam kinect+rgbdslam.launch 
  ... logging to /home/sam/.ros/log/07543c9e-f807-11e1-8779-20cf30a23845/roslaunch-sam-21581.log
  Checking log directory for disk usage. This may take awhile.
  Press Ctrl-C to interrupt
  Done checking log file disk usage. Usage is <1GB.

  while processing /opt/ros/fuerte/stacks/openni_camera/launch/openni_node.launch:
  Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'/opt/ros/fuerte/stacks/openni_camera/launch/openni_node.launch'
  sam@sam:/media/Data/code/ros/slam/rgbdslam$

How to solve it?

Thank you~

I get rgbdslam to work as follows

roslaunch openni_launch openni.launch
rosrun rgbdslam rgbdslam

The topics that are necessary for rgbdslam node are published by openni.launch file. Just don't use kinect+rgbdslam. This has been working for me

The openni drivers have changed in fuerte, and the kinect+rgbdslam.launch launch file is looking for the electric openni_camera launch file. You can fix this by changing the kinect+rgbdslam.launch file as such:

change

<include file="$(find openni_camera)/launch/openni_node.launch"/>

to

<include file="$(find openni_launch)/launch/openni.launch"/>

Tip: Make sure you have installed openni_launch, as it is no longer included in the openni_camera package.

Does the file or directory exist? Is openni_camera installed?
As you use fuerte, the launch file might just not be written for fuerte, thus you need to adapt it. (Basically start the kinect with its launch file).
