Thank you for your reply!
so deployingf to jetson 4.6 with jetpack4.5 argument to try on jetson with zed2?
It would require to buils the sample app somehow?
how to build it with analogy to

bazel build //apps/samples/zed_camera

there is no elbrus sample app at the Host PC

./../engine/engine/build/deploy.sh --remote_user user -p //apps/samples/elbrus_visual_slam_zed:elbrus_visual_slam_zed-pkg -d jetpack45 -h 192.168.x.x

jetpack 4.6 argument doesn't seem supported for jetson deployment?
also can not find as for now deployment line for the elbrus zed svo
Ffrom the instruction:

The “elbrus_visual_slam_zed” sample application uses the ZED camera, which performs software undistortion inside the StereoLabs SDK.

but there is no such app in the sample app folder
It only has

[AndreV84]

where to get these files on jetson? packages/visual_slam/apps/elbrus_visual_slam_zed_python.py
trying to build on the Host PC with

bazel build packages/visual_slam/apps/elbrus_visual_slam_zed

@hemalshahNV but how to deploy it to jetson once built?

[hemalshahNV]

Are you using Elbrus in Isaac SDK? If so, you’ll want to post in our dev forums so other Isaac SDK users can help.

@hemalshahNV Thank you for your response: "Are you using Elbrus in Isaac SDK?"
No, I used the ROS node with realsense without the IsaaC.
However as you confirmed that zed2 works wit hElbrus, coudl you extend if it is supported in a standalone mode [ like with realsense] or with Isaac + Elbrus mode? Both? neither of the two?
Moreover, the linked reference thread is at the first message in the github issues post
https://forums.developer.nvidia.com/t/will-it-work-with-the-zed2-the-elbrus/196452

[AndreV84]

anyway posted at both places, could you extend on steps to run zed2 with elbrus anyhow please e.g. in the setup you confirmed previously, please?

[hemalshahNV]

I'm afraid I'm not following what you're trying to do exactly, but let me see if I can help on the ROS-side of the conversation here and address the Isaac SDK part of it in the Dev Forum post you made (my bad, did not notice the link in your first post). You would first have to go prepare the Zed2 ROS2 packages here. Then, there is an Isaac ROS launch file that should bring up the VO nodes with topics remapped for Zed. All you would have to do is launch the ZED camera ROS2 node then launch this Isaac ROS VO launch file and you should be up and running. We had configured the Realsense version of this launch file to also bring up the Realsense camera node as well but didn't have a chance to do something similar for ZED though, so we had to leave launching the ZED camera node up to the user.

[AndreV84]

@hemalshahNV
Thank you for your reply.
I will be trying to setup the zed2ros2 package to run it on jetson in foxy2 container docker implementation provided by you.
But I will have to separately copy the file https://github.com/NVIDIA-ISAAC-ROS/isaac_ros_visual_odometry/blob/main/isaac_ros_visual_odometry/launch/isaac_ros_visual_odometry_zed2.launch.py manually to Jetson, right? or it won't work with just copying the single file but would need to deploy also the environment with Isaac[bazel] from Host PC to Jetson?

[AndreV84]

@hemalshahNV
after installing zed2 srapper copying pyhton script getting this on ros2 foxy jetson

after running zed2 node.:

ros2 launch zed_wrapper zed2.launch.py

how to run the python file

ros2 launch isaac_ros_visual_odometry isaac_ros_visual_odometry_zed2.launch.py 

like that?

 ros2 topic echo /visual_odometry/tf_stamped

However the output is empty of the latter.
Any ideas?

You will need to checkout the Isaac ROS VO repository to your Jetson and build the packages within using the ROS2 standard colcon. There is no Bazel involved. Your steps in the subsequent post look right. You may want to check that the topics are all mapped correctly with ros2 topic list and ros2 topic info to make sure everything is wired appropriately.

does zed2 need certain firmware? sdk version? I just installed the latest available sdk from stereolabs website. zed2 node seems working with it as ther is e..g pose topic poblished
does the phrase below reffer to docker container?

The setup is systemwide, no container is used

Are you seeing any traffic on topic /zed2/zed_node/left/image_rect_gray? (ros2 topic hz /zed2/zed_node/left/image_rect_gray) The isaac_ros_visual_odometry_zed2.launch.py launch file should work remap to the topics coming from the Zed camera in your ros2 topic list, so everything should be wired together. We need to confirm that Zed camera is actually outputting anything.

so for zed2 there is no launch script for vizualization anyhow with issac sim? else?
the most simple way to vizualise will be which from the text outputs for zed2? Thanks

Could you confirm there is still no way to run elbrus on Jetson with basel? only with ros2?

@hemalshahNV
We managed to run zedm with prior version of the odometry
However, it only seem to generate one topic as resulting output
/visual_odometry/tf_stamped
is that correct?

[AndreV84]

@hemalshahNV does it have zed support by now? with the most recent release?
Thanks

[hemalshahNV]

We have not developed any ZED support specifically but there is no reason that it should not work that we know of if you setup the ZED SDK and everything properly.

[AndreV84]

@hemalshahNV Thank you for following up!
However, while installing the SDK from stereolabs is not an issue at all, but a trivial task,
the problem is to get zed stereolabs humble wrapper node installed in humble container supplied from you.
Neither it seems to build even if to update the os to 22.04 to get apt ros humble support
If you will have any luck with testing the zed coherence with slam or nvblox, let me know please

@hemalshahNV hello,
Was isaac_ros_visual_odometry_zed2.launch.py deleted from the repository? I wonder what were the launch parameters for ZED and visual slam nodes.
I tried making ZED camera work with Isaac Visual SLAM, but unfortunately I'm getting messages that the tracker got lost.
I've remapped all the frames, tried disabling ZED's tf2, nothing helped..

[hemalshahNV]

@shtern94 , yes, we removed the ZED launch file because it was not being tested regularly at the time as changes to the Stereolabs SDK were coming through. In an upcoming release, we're working on adding more complete ZED support and currently debugging ZED and Isaac ROS Visual SLAM in fact. When we find anything, I'll report back.
