Hi folks :-)

Apologies for the long post but I have been trying for three days now to install, build and test RGBDSLAM without any success and am getting rather frustrated... surely it shouldn't be so hard :-)

I am quite experienced and have followed the instructions laid out in http://www.ros.org/wiki/rgbdslam and http://ros.org/wiki/electric/Installation/Ubuntu etc. to the letter and have tried all sorts of fixes suggested here, and on other sites, including starting from scratch with fresh Ubuntu installs twice, to no avail.

So, PLEASE could someone run through a fresh install and provide up to date detailed instructions as I see I'm definitely not the first to have build problems.

This is what Ive done, three times, following predominantly http://www.ros.org/wiki/rgbdslam, thus far:

1) Installed absolutely clean Ubuntu 11.10 64bit version (confirmed with /etc/issue and the output of uname -m)

2) Installed ROS Electric as required as per http://ros.org/wiki/electric/Installation/Ubuntu. Commands entered in "Terminal" as follows:

a. sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu oneiric main" > /etc/apt/sources.list.d/ros-latest.list'

b. wget http://packages.ros.org/ros.key -O - | sudo apt-key add –

c. sudo apt-get update

d. sudo apt-get install ros-electric-desktop-full

e. echo "source /opt/ros/electric/setup.bash" >> ~/.bashrc

f. . ~/.bashrc

3) Installed QT4 (QT Creator) via Ubuntu Software Center

4) Setup RGBDSLAM again as per http://www.ros.org/wiki/rgbdslam

a. mkdir -p ~/ros

b. echo 'export ROS_PACKAGE_PATH=~/ros:$ROS_PACKAGE_PATH' >> ~/.bashrc

c. source ~/.bashrc

d. svn co http://alufr-ros-pkg.googlecode.com/svn/trunk/rgbdslam_freiburg/rgbdslam

e. svn co https://code.ros.org/svn/ros-pkg/stacks/vslam/trunk/g2o ~/ros/g2o

f. rosmake --rosdep-install rgbdslam

This immediately failed with:

[ rosmake ] Packages requested are: ['rgbdslam'] [ rosmake ] Logging to directory/home/mike/.ros/rosmake/rosmake_output-20120121-085503 [ rosmake ] Expanded args ['rgbdslam'] to:[] [ rosmake ] WARNING: The following args could not be parsed as stacks or packages: ['rgbdslam'] [ rosmake ] ERROR: No arguments could be parsed into valid package or stack names.

5) So I checked:

a) sudo apt-get install libglew1.5-dev libdevil-dev libsuitesparse-dev No problem

b) Tried to fix .bashrc adding various combinations and orders of export and source commands (not detailed in instructions)

... " enable programmable completion features (you don't need to enable " this, if it's already enabled in /etc/bash.bashrc and /etc/profile " sources /etc/bash.bashrc). if [ -f /etc/bash_completion ] && ! shopt -oq posix; then . /etc/bash_completion fi

export ROS_PACKAGE_PATH=~/ros:$ROS_PACKAGE_PATH source /opt/ros/electric/setup.bash ...

c) Tried to fix electric setup.sh with other changes (also not detailed in instructions) http://answers.ros.org/question/222/error-when-compiling-rgbdslam-for-kinect ... "!/bin/sh

export ROS_ROOT=/opt/ros/electric/ros export PATH=${ROS_ROOT}/bin:${PATH} export PYTHONPATH=${ROS_ROOT}/core/roslib/src:${PYTHONPATH} export ROS_PACKAGE_PATH=/opt/ros/electric/stacks:/home/mike:/home/mike/ros/ros-pkg:~/ros_workspace:$ROS_PACKAGE_PATH if [ ! "$ROS_MASTER_URI" ] ; then export ROS_MASTER_URI=http://localhost:11311 ; fi ...

Tried incrementally odd combos of ROS_PACKAGE_PATH - now you ... (more)

If you followed this steps literally I think the problem is 4d/e. This svn checkouts like this will end up in your home, not ~/ros and thus cannot be found in ROS_PACKAGE_PATH.

So you should cd ~/ros before the svn co calls.

Problem resolved, VMWare was unfortunately the culprit.

I rebuilt the whole system, yet again, from scratch on a bootable Ubuntu 11.10 64bit partition and it worked imediately (tho I did have to install GSL independently again Felix).

Now I think I have a more fundamental issue, perhaps with an easy, but expensive solution. I think my Intel I3 M330 dual 2.13GHz laptop, with 4GB ram, is simply not up to the task.

The CPU is maxed out whilst Im capturing data and the resultant frame rate is very slow, which in turn is leading (I suspect) to greater deltas between analysed frames, less matching and ultimately, my generated maps are often VERY poor.

(I have tried moving the camera very slowly but this only helped a little bit)

Also, the 4GB fills up extremely quickly so I'm prettly much limited to small room maps.

Do you guys have any advice on the effectiveness of high spec cpu's with RGBDSLAM - as Ive been looking for an excuse to get a new speedy machine:-)

Thanks you all for your patience and superb advice.

"Viel hilft viel" is a german saying :-). RGBDSLAM makes good use of many cpu cores. A good 3D graphics card will speed up the GUI and SIFTGPU features. CUDA makes the latter even faster than GLSL. For online usage you need as much RAM as you can get. Offline you can work around this.

Felix Endres ( 2012-01-23 19:31:36 -0500 )edit

However, you could try to not subscribe to the point cloud topic of the kinect, this will shift processing requirements from the driver to RGBDSLAM. Then use the ...skip_step parameters, see the example launchfiles. Do not store the pointclouds in RAM, run without GUI (see params) if not required.

Felix Endres ( 2012-01-23 19:34:45 -0500 )edit

Thats superb news, time to buy the i7, 8gb laptop Ive been eyeing out. The I will look at running without the GUI, and I can wait to get stuck into the trying to use color octomaps........ Thanks for you superb help Felix, we can mark this as answered :-)

Mike Moore ( 2012-01-24 20:35:44 -0500 )edit

You're welcome. I'd suggest you mark dornheges answer as correct answer, since he spottet the original problem the title relates to.

A good question, but please ask it separately. This is a Q&A forum, not a discussion forum.

For something as complex as this, I recommend using rosinstall to manage your source checkouts.

There are some other hints from this question, which explains the difference between system dependencies and ROS package dependencies.

Ahaaa, got the build and Kinect recognition going at last - did a completely fresh install and found I had to also install GSL for the default build to complete: (sudo apt-get install gsl-bin; sudo apt-get install libgsl0-dev) and then GTK for the pixbuf requirement (sudo apt-get install gtk2-engines-pixbuf) before the GUI would launch.

But now, RGBDSLAM is now building fine and is recognizing the Kinect on launch but unfortunately still no data/image from the Kinect ever appears on the GUI. It just says "Waiting for monochrome, depth and motion" information...

The terminal displays:

process[rgbdslam-7]: started with pid [17347] bool g2o::HyperGraphActionLibrary::registerAction(g2o::HyperGraphElementAction): creating collection for "writeGnuplot" bool g2o::HyperGraphActionLibrary::registerAction(g2o::HyperGraphElementAction): creating collection for "draw" ... So,what do I need to do now? :-)

Do I need to install some sort of viewer or support package, or specific graphics drivers, or is running Ubuntu as a VM possibly causing problems (unlikely)?

So close, all help appreciated :-)

Hmmm, Ive been trawling around and perhaps a) I need to install RVIS or something similar, or b) this is a known issue relating to OpenNI not running well on a VMWare VM... Is there any way around this - I don't want to reinstall AGAIN, and I blew my bandwidth limit doing this four times already :-)

Mike Moore ( 2012-01-22 23:28:18 -0500 )edit

I'm not sure, what you are trying to achieve with reinstalling. Unless you really want to record a clean way with every keypress for a full setup, it is not necessary. By installing packages, you don't really make the system "worse" and any unwanted steps can be undone.

dornhege ( 2012-01-23 00:23:10 -0500 )edit

VMs might be problematic, but the errors seem to suggest there is no data. You could test with rviz to display the raw kinect data.

dornhege ( 2012-01-23 00:24:33 -0500 )edit

From the side of RGBDSLAM this all looks good. You can verify it with a bagfile as suggested in my comment above. I would suspect that the virtual machine may indeed be problematic.

Felix Endres ( 2012-01-23 03:17:54 -0500 )edit

BTW, I don't have gsl-bin installed, so it's probably not required.

Thanks for your speedy answer Dornhege :-)

I think Ive got the build going 100% (reordering calls in .bashrc seems to have worked) but am still stuck right at the last hurdle - I can even see the RGBDSLAM GUI - so am tantalizingly close :-)

I installed the "openni_kinect" package as per http://www.ros.org/wiki/openni_kinect using the command "sudo apt-get install ros-electric-openni-kinect" - no problem - and have connected the Kinect.

But still, whenever I launch RGBDSLAM with "roslaunch rgbdslam kinect+rgbdslam.launch" (or "roslaunch openni_camera openni_node.launch" I get the following error:

'[ INFO] [1327243304.290757975]: [/openni_node1] Number devices connected: 1
'[ INFO] [1327243304.291324641]: [/openni_node1] 1. device on bus 001:10 is a Xbox NUI 'Camera (2ae) from Microsoft (45e) with serial id 'A00365807452048A'

This appears to be a common problem and I have tried:

Killing XnSensorServer (with 'Killall XnSensorServer') at different pre/post launch stages, to ensure its shut down, this had no effect.

It was suggested somewhere else that I run 'echo “blacklist gspca_kinect” > /etc/modprobe.d/blacklist-psengine.conf' to prevent an Ubuntu service from interfering - no luck.

and tried to set the following in case it would help - but am not sure if I did so correctly: ROS_HOSTNAME="localhost" ROS_MASTER_URI="http://localhost:11311"

My USB setup looks fine I think:

mike@ubuntu:~$ lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 001 Device 009: ID 045e:02ad Microsoft Corp. Xbox NUI Audio
Bus 001 Device 010: ID 045e:02ae Microsoft Corp. Xbox NUI Camera

So, what could it be??? Have I forgotten to install something, or set something else somewhere???

All help hugely appreciated, so close :-)

Thanks, Mike

P.S. This is the start of the output when I execute "roslaunch rgbdslam kinect+rgbdslam.launch"

Thanks Joq, but surely this shouldn't be all that complex, or obscure, a process as, all I'm trying to do is to get RGBDSLAM working on a clean Ubuntu install.

i.e.: 1) Setup clean OS (Ubuntu 11.10 64bit) 2) Setup ROS (electric) 3) Setup and build RGBDSLAM 4) Setup Kinect drivers 5) Run RGBDSLAM

After loads of work, I'm finally up to stage 4, still without being able to contribute anything to further development of RGBDSLAM.

With clear, tested, environment setup instructions there shouldn't be any missing packages. Can rosinstall help me out here?

P.S. To install the Kinect drivers I simply ran 'sudo apt-get install ros-electric-openni-kinect'. Perhaps I need to build them as per the Source Based Installation in http://www.ros.org/wiki/openni_kinect... any thoughts?

Hi, sorry for your troubles your detailed problem report is appreciated. I think you solved the problem installing rgbdslam, so I suggest opening a new question for the openni problem. Anyway, here my thoughts: You should not need to install from source. I am running the same setup and it works.

Felix Endres ( 2012-01-22 18:55:50 -0500 )edit

I also had the error you described, but I always "solved" it by restarting the openni launch file. Maybe others can help more with this. I think, there are also some questions about this on this site.

Felix Endres ( 2012-01-22 19:01:52 -0500 )edit

If you want to test rgbdslam without kinect, download a sequence from http://cvpr.in.tum.de/data/datasets/rgbd-dataset/download and use "rosbag play <filename.bag>". Make sure to set the appropriate topics (i.e. clear the "topic_points" parameter and set topic_image_mono to /camera/rgb/image_color).

Felix Endres ( 2012-01-22 19:03:56 -0500 )edit

Thanks Felix, no worries, I will persevere :-) I'm starting again from scratch with another fresh Ubuntu install - hopefully I will have more luck this time... UPDATE: Hit same RGBDSLAM build errors again "fatal error: gsl/gsl_linalg.h: No such file ..." Hmm

Mike Moore ( 2012-01-22 20:48:06 -0500 )edit

Incidentally Felix, what do you mean by "restarting the openni launch file"? Is this a new Terminal session or is there another method I haven't tried? I know its a big hassle, but if you're able to do a fresh line-by-line test install, that would clarify all these issues and solutions. THANKS :-)

Mike Moore ( 2012-01-22 20:55:40 -0500 )edit

GSL is actually set as a dependency in manifest.xml/rosdep.yaml, so "rosmake --rosdep-install rgbdslam" should have pulled it automatically. By restarting the launch-file I mean killing it (ctrl-c) and starting it again. No magic here.

Im not using VMWare and I have the same problem. The rgbdslam gui opens up but nothing is displayed. the kinect is connected and powered correctly but the infrared never comes on and the led on the kinect just keeps flashing green. Im using ros-electric on the latest oneiric ubuntu.

I keep getting: creating depth generator failed. ,Reason: The network connection has been closed!

Has anyone been able to finalize a fix for this? Any help plz :S
