VTK issue when launching rtabmap

[felron124]

Hello, I am trying to use a Kinect with a raspberry pi with ros melodic on Debian Buster. When I install rtabmap from source and run it I get the error below. I am very new to linux so I would appreciate some help fixing this issue in layman's terms. Thanks.

It seems VTK is expecting another OpenGL version (depending if VTK has been built for mobile but used in a desktop environment). I got similar issues on jetson some years ago, that required to rebuild VTK and QT from source... which you don't want to do because it is too long (days to compile everything right). Rendering would be very laggy on RPI, I suggest to use ROS and visualize the result on another computer. I never visualize rtabmap on RPI, always on a remote computer, the RPI is not meant to render 3D graphics.

[felron124]

Yes, the plan is to use another computer but I thought that rtbabmap needed to be installed on both RPI and the computer? I forgot to give full context in my original post but I am following this tutorial RGB-D SLAM With Kinect on Raspberry Pi 4 ROS Melodic which is saying to install rtabmap on the RPI. Thanks.

i have similar error

Could you help point me in a direction where I can find out how to visualize rtabmap on a remote computer? Like I said in the original post, I'm very new to all this so I'm not sure where to look. Also, just to clarify, are you saying its possible to have the kinect connected to the RPI and then have the rendering done on a remote computer? Thanks.

[matlabbe]

@felron124 With ROS it is possible, see http://official-rtab-map-forum.206.s1.nabble.com/RGB-D-SLAM-example-on-ROS-and-Raspberry-Pi-3-tp1250.html

For RPI4 related issues with VTK rendering, I'll need to reproduce it on my RPI4 later to be able to help more.

[felron124]

Ok, thank you for the help. Is it possible to have the computer running windows or will I need to use linux?

[matlabbe]

If you just want to try hand-held kinect mapping, that can be done with windows binaries: https://github.com/introlab/rtabmap/releases/tag/0.21.0 (and check this tutorial)

To use more custom inputs, the rtabmap_ros package on ubuntu is the easiest way.

[felron124]

@matlabbe Sorry its been awhile but I'm back on this now. I will use ubuntu on a remote laptop to process the mapping. I have 3 questions if you don't mind. 1. Does it matter what version of ubuntu I use, 2. the packages installed during this tutorial ,RGB-D SLAM With Kinect on Raspberry Pi 4 ROS Melodic, am I right in saying that these also go on the remote laptop and 3. is ros melodic the only thing that goes on the pi? I know that 2 and 3 arent questions related to rtabmap but you're the only person that I've found that has an idea of this. Thanks.

Edit: On the main page of the rtabmap github, it says that the ROS melodic build is disabled. Does this mean that rtabmap wont work with melodic at all? If so then I'm guessing Ubuntu 20.04 + noetic is the way to go in relation to the remote pc.

[matlabbe]

ROS melodic is EOL, so not supported anymore, though it may still work on 18.04+melodic. However, if you can install 20.04 on RPI4 with Noetic, I strongly suggest to do that. So if you have both computers with ROS noetic, that is the best.

[felron124]

@matlabbe I don't think 20.04 desktop for rpi is available anymore but the server version is. Will the server version work fine since the visual map will be on the laptop or is the desktop version needed? Also, with the remote laptop visualising the map, is the kinect supposed to be connected to the pi or the remote laptop? Thanks.

Edit: After some research. I found that 20,04 desktop never existed but instead you have to install the server version and then install some packages. I'd still like to know about where the kinect is supposed to be connected to.

[matlabbe]

Is the laptop following RPI4 (e..g, laptop sitting on the robot)? If so, the kinect could be connected to laptop if rtabmap is running on it. If rtabmap should be ran on RPI4 or that the laptop won't follow the pi, connect kinect to RPI4.

Ubuntu Mate 20.04 should work on RPI4, though the link looks dead, only 22.04 is officially available. ROS noetic cannot be installed on 22.04. Digging more, the 20.04 image may be available from here: https://releases.ubuntu-mate.org/20.04/arm64/

[felron124]

@matlabbe The laptop wont be sitting on the robot, the pi and the kinect will be on the robot. So are you saying that the kinect has to be connected to the device that has rtabmap installed on it? Thanks.

[matlabbe]

No the kinect should be connected to the robot, thus the Pi on the robot. You can then have the choice to launch rtabmap node on RPI (robot) or streaming the kinect images thought WiFi to laptop running rtabmap.

[felron124]

@matlabbe Ah ok, I want stream the images to the laptop. Do I have to install freenect on both devices or just the pi and is the link you sent earlier how I execute it when everything is set up? Thanks.

[matlabbe]

Maybe a useful link for you: http://wiki.ros.org/rtabmap_ros/Tutorials/RemoteMapping

You only have to install freenect on RPI, and rtabmap on laptop.

[felron124]

@matlabbe I created the file but when I run it I got an error saying "Failed to load nodelet [/camera/rgbd_sync] of type [rtabmap_ros/rgbd_sync] even after refreshing the cache: According to the loaded plugin descriptions the class rtabmap_ros/rgbd_sync with base class type nodelet::Nodelet does not exist.". I then edited it like it says on the page , changing it to "args="standalone rtabmap_ros/rgbd_sync", but then got the same error. I then reverted back to the original code added the "" on line 2 but got the same error again.

[matlabbe]

You should now use rtabmap_sync/rgbd_sync (see Migration guide for latest rtabmap_ros version)

[felron124]

@matlabbe Since I just installed it, I presume the new package names are already installed? Do I just have to replace the old names in the launch file? Thanks.

[matlabbe]

If you are using a custom launch file using the old interface, yes. If you are using a launch file that is installed from that rtabmap version and it fails, it is a bug (which launch file are you using if so?), as all launch files should have been updated.

[felron124]

@matlabbe I'm using the launch file in the site you linked http://wiki.ros.org/rtabmap_ros/Tutorials/RemoteMapping, so I'll just have to change the names. I wasn't aware that there are other launch files, where can I find a list of them? Thanks.

[matlabbe]

I updated the tutorial: http://wiki.ros.org/rtabmap_ros/Tutorials/RemoteMapping

Other launch files: https://github.com/introlab/rtabmap_ros/tree/master/rtabmap_demos/launch https://github.com/introlab/rtabmap_ros/tree/master/rtabmap_examples/launch https://github.com/introlab/rtabmap_ros/tree/master/rtabmap_launch/launch

[felron124]

@matlabbe Got it working!!! Thank you. One thing though, I get the following message on the pi during runtme "[ WARN] [1693418333.817639794]: The time difference between rgb and depth frames is high (diff=0.010220s, rgb=1693418333.811776s, depth=1693418333.801557s). You may want to set approx_sync_max_interval lower than 0.01s to reject spurious bad synchronizations or use approx_sync=false if streams have all the exact same timestamp". Where is approx_sync_max_interval or is there another way to fix this? Also, on the remote laptop, I get the following "[WARN]: Could not get transform from odom to camera_link after 0.2000000 seconds (for stamp=1693418333.76238)! Error='Lookup would require extrapolation 134.037218s into the future. Requested time 1693418333.76223826 but the latest data is at the time 1693418199.725055695, when looking up transform from frame [camera_link] to frame [odom]. canTransform returned after 0.201367 timeout was 0.2.". Thanks.

[matlabbe]

For approx_sync_max_interval, it can be set as parameter for rgbd_odometry and rtabmap nodes.

For the 134 sec difference between the timestamps, I am not sure where/how the odom is computed, but you may have to synchronize the clocks between your laptop and the RPI4 (using ntpdate or chrony)

[felron124]

@matlabbe Works really well now, thank you. One question on the tutorial you linked http://wiki.ros.org/rtabmap_ros/Tutorials/RemoteMapping , I don't think I'm reading the flowchart correctly but is there a stack or a way to take the data and create controls for the robot? If not, do you have a stack that you would recommend for go-to-goal technique? Thanks.

[matlabbe]

rtabmap is generally only for mapping. If you need to navigate, I'll suggest to look at the navigation stack of ROS (e.g., move_base). There is an example of integration between move_base and rtabmap here: http://wiki.ros.org/rtabmap_ros/Tutorials/MappingAndNavigationOnTurtlebot
