Hi guys, i'm trying to create a ndt_mapping using our bag file, but isn't successful.

First, according to this page (here)

  1. Go to Simulation tab and select arosbag
  2. Click "Play" and click "Pause
  3. Click Computing tab and select ndt_mapping
  4. Click RViz button
  5. Go back to Simulation tab and click Pause to start mapping

And no point cloud is shown in rviz.

I test the ROSBAG Demo according to this page (here)

And no point cloud is shown in rviz, too.

I using ubuntu 18.04/melodic Autoware:1.12 (use source install)

To visualize using rviz, you should set TFs properly. I guess this is the cause.

Could you try these additional steps?

  1. Click "TF" in Setup tab
    • for /base_link to /velodyne
  2. Click "TF" in Map tab after Referencing tf.launch in sample moriyama data
    • for /world to /map
  3. Re-launch ndt_mapping
    • Just in case

If not resolved, please give us these information.

  1. Results of rosrun tf view_frames (frames.pdf)
  2. ScreenShots of your runtime_manager and rviz
  3. (If any error message is shown in rviz) the error messages

@scarlet191101 Have you solved this problem?

I don’t have much time to try recently.

Click "TF" I have tried, but it is not effective

I don’t know why I often crash when I last tested.

I will test it when I have time.

Thank you~

same issue as above. I tried your suggestions but got this error when relaunching MAP.

RLException: while processing /home/<myname>/.autoware/data/tf/tf.launch: Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'/home/<myname>/.autoware/data/tf/tf.launch'

Detected dot version 2.40 frames.pdf generated I don't know how to attach a file here but here is a cut and paste of the .pdf. It shows world connected to map and base_link connected to velodyne.

3) Rviz error: TF: No transform from [base_link] to frame [world] No transform from [velodyne] to frame [world] Points Raw: For frame [velodyne]: No transform to fixed frame [world]. TF error: [Lookup would require extrapolation into the past.

@avdev Thank you for giving the information. If possible, could you upload the data to Google Drive or some online storage services and share the link?

As for the error, I think the cause is you are launching nodes BEFORE starting rosbag play. When we play rosbag, rosparam use_sim_time will be true. We need to launch nodes after that in order to use the simulation time.

Thanks for the feedback.

I tired it again making sure to start the rosbag play before launching the map node. I am not sure how to check the use_sim_time.

Here are the screen shots and .pdf you asked for.

A second problem that I did not mention earlier is that RuntimeManager has screen tearing making it hard to do more than 2 steps. Any ideas there?

also I did not find the tf.launch in sample moriyama data but used this instead for #2 in your suggestions. /home/<username>/

I've recorded my operation and uploaded it to here.

What I did are:

  1. Download files from here
  2. Setup Autoware according to this page
    • If you are using ROS Melodic, I recommend using master version instead of v1.12, or please wait v1.13 which will be released soon
  3. Launch runtime_manager
  4. Play and pause .bag file
  5. Launch tf of velodyne and map
    • It seemed ndt_mapping requires velodyne-tf BEFORE ndt_mapping
  6. Launch ndt_mapping
  7. Launch Rviz
  8. Cancel the pause of .bag file
  9. Velodyne's points can be seen in Rviz

Thank you,Kenji Miyake.

I have been able to execute it a while ago, and I'm sorry to respond to it until now.

First, I started testing from the bag file.

Encountered rviz crashes, so I changed to a computer to test.

Now it can be successfully executed, and also successfully executed with its own bag file.

I've recorded my operation and uploaded it to here
