the entry point script in the documentation of Setting up Isaac ros is wrong. I wasn’t able to use that.
What version of Isaac ROS are you using?
Please specify what’s wrong with the entrypoint and what fixes you applied. They could help other users.
Hey Myzhar, I in my case totally had to uncomment the whole entry point in the docker config that it is not used. Everything else which does user changes etc. does cause errors.
I just donwloaded the actuall Isaac ros version like in your description.
Have you tried to use Isaac ROS 3.2?
When the documentation was written, the current version v4.x had not been released yet.
I don’t know how and where to find the version. I just did run_dev.sh like in your description and the docker was pulled.
How can I elsewise reset this when you say that it is not supported?
If you used the correct command at step #5 here, then you are using Isaac ROS 3.2
Yes I have done it with Isaac Ros 3.2 where the entrypoint was false
But can you give me a hint how I can see the April Tags in Rviz in the way how you could see? It does not successfully show the result on my side.
Is it always mendatory that the april tags do have fixed positions? In real scenarios often the positions are not known due to differences.
It’s not. They can move.
Are you using the correct configuration? Are the April Tags detected?
Do you get something in the /tag_detections topic?
Im using this tutorial yes. I see the topic on command line but not on rviz. That is my greatest problem. Therefore I cannot for sure answer your question. I don’t know how I have to adjust rviz. There this topic is not shown. And what is then the reference frame when you want to drive with a robot? Somewhere must be the informations or even that not?
There’s nothing specific on rviz2, only the TF with the pose of the target if it has been detected.
Simply add a TF visualizer plugin:
The name changes according to the type and ID of the tag that you are using.
Is the
message populated? You can get all the information in the content of the message.
I can’t see that on rviz on the command line it is /zed/zed/tag_detections yes but in rviz in tf no chance
Please post a screenshot showing all the frames available in the TF view.
