Problems building and using OCTOMAP with RGBDSLAM

edit

Hi again folks (I'm back after a short stint on another project)

After some work I managed to get RGBDSLAM running nicely (discovering the long way round that it does NOT work on a VMWare Virtual Machine) and am now struggling to build and use OCTOMAPS.

I have gone through all the RGBDSLAM information and tons of references in ROS Answers without success. There are however some rather different instructions of how to achieve this so, please can you clarify which is the most effective and up to date.

RGBDSLAM is working fine so, here is what Ive done thus far:

FIRST ATTEMPT (as per section 4.1 of http://www.ros.org/wiki/rgbdslam#Octomaps)

1) GET SOURCE: Checked out latest OCTOMAP experimental code

svn co http://alufr-ros-pkg.googlecode.com/svn/branches/octomap_mapping-experimental/

2) BUILD: Built experimental OCTOMAP Server

cd ros/octomap_mapping-experimental/build/

cmake ..

make

(Seemed to complete with no errors or warnings - perhaps Ive done this wrong?)

3) LAUNCH BY ITSELF: Launched OCTOMAP server by itself to test

roslaunch rgbdslam octomap_server.launch

But I get the following error (perhaps its because RGBDSLAM isn't running):

started core service [/rosout] ERROR: cannot launch node of type [octomap_server/octomap_server_node]: Cannot locate node of type [octomap_server_node] in package [octomap_server]

5) LAUNCH AFTER RGBDSLAM So, as per the instructions I first launched RGBDSLAM using:

roslaunch rgbdslam kinect+rgbdslam.launch

I then captured a scene then tried to launch the OCTOMAP server (obviously using a new Terminal - is this correct?) with:

roslaunch rgbdslam octomap_server.launch

but again I get the following error:

core service [/rosout] found ERROR: cannot launch node of type [octomap_server/octomap_server_node]: Cannot locate node of type [octomap_server_node] in package [octomap_server] No processes to monitor shutting down processing monitor... ... shutting down processing monitor complete

4) CONFIGURATION: I made the following modifications but they didn't help:

Edit (a copy of) octomap_server/launch/octomap_mapping.launch such that the mapping from cloud_in goes to /rgbdslam/batch_clouds and the value of frame_id is "openni_camera"

Are these changes necessary? Are there more that should be made?

SECOND ATTEMPT (as per section 4 of http://www.ros.org/wiki/rgbdslam/evaluation#Octomapping_Requirements)

1) SOURCE: Checked out latest OCTOMAP evaluation code

svn co https://alufr-ros-pkg.googlecode.com/svn/branches/octomap_mapping_color ~/ros/octomap_mapping_color
svn co https://code.ros.org/svn/wg-ros-pkg/stacks/motion_planning_common/trunk ~/ros/motion_planning_common

2) BUILD: Built evaluation OCTOMAP Server

rosmake motion_planning_common
rosmake --rosdep-install octomap_mapping_color

Unfortunately NEITHER of these currently build without errors so I was unable to proceed here too.

So, please could someone clarify, step by step, how I go about setting up and run OCTOMAPS with RGBDSLAM.

Many thanks (and sorry I keep struggling with these seemingly straightforward things :-))
