CORRUPTED SDK INSTALLATION - isaac sim ROS2

[efesendil]

Hello,

I am trying to connect isaac sim to ROS2 but the command ros2 launch zed_wrapper zed_camera.launch.py camera_model:=zedx sim_mode:=true fails and so ros2 launch zed_display_rviz2 display_zed_cam.launch.py camera_model:=zedx sim_mode:=true

However I can visualize the data through ZED_Depth_Viewer

Can you please help me to solve this issue ?

[Myzhar]

Hi @efesendil
it seems that the ZED SDK is not properly installed on your PC.

Can you please run the ZED Diagnostic tool and send me the diagnostic report that it generates?

[efesendil]

Hi,
thanks for the reply.
Here is the report

ZED_Diagnostic_Results.json (4.9 KB)

[Myzhar]

According to the report, the software on your PC is correctly installed.

Can you try to open the virtual stream with ZED Depth Viewer and check that the depth is correctly extracted?

[efesendil]

Actually I sent you the screenshots from ZED tools in my first post, I wanted to send them in advance in case if needed. Can you please check the first post for the screenshots and the terminal loggings ?

It seems like ZED_Depth_Viewer can correctly show the depth.

Thanks.

[efesendil]

Hello,

Can you please provide me any solution ideas to this ?

[BenjaminV]

Hi,

Can you run

glxinfo | grep "OpenGL vendor"

and tell me if it outputs your Nvidia GPU or not please?

if not, run:

sudo prime-select nvidia
sudo reboot

[efesendil]

Hi,

thanks for the reply,
glxinfo | grep "OpenGL vendor" outputs
OpenGL vendor string: NVIDIA Corporation

[efesendil]

Hello again,

I’ve managed to solve the issue, i can now visualize the data through RVIZ. Thanks for your support !
I only have one quick question please, i can publish data to /zed/zed_node/path_map and /zed/zed_node/pose however the camera doesn’t move, it kinda draws the path on rviz but the camera doesn’t following the path? What could be the reason ?

Can you please provide information concerning the cause of the issue and how you solved? This will be useful for other customers facing the same problem.

Can you please provide more information? A video recording, for example, will be very useful to understand the problem.

[efesendil]

Yes, definitely.

• Make sure you’re up to date with the repository: GitHub - stereolabs/zed-ros2-wrapper: ROS 2 wrapper for the ZED SDK
• Run the build command in the repo and source install/setup.bash
• Wait until “ros2 launch zed_wrapper zed_camera.launch.py camera_model:=<camera_model>” finishes the installation before launching “ros2 launch zed_display_rviz2 display_zed_cam.launch.py camera_model:=zedx sim_mode:=true”

@Myzhar, this is not a bug, but being able to see the installation steps during this process would be helpful. I’ve noticed that you can only see the percentage and remaining installation time when you launch ZED_Depth_Viewer in another terminal. However, it only displays the status at launch and doesn’t update the terminal, which is probably why I thought my command had frozen the process.

About the issue on rviz;
here is the rviz and isaac sim

• then on another termianl, i’m running

ros2 topic pub /zed/zed_node/path_map nav_msgs/msg/Path "{
  header: {
    frame_id: 'map',
    stamp: {sec: 0, nanosec: 0}
  },
  poses: [
    {
      header: {
        frame_id: 'map',
        stamp: {sec: 0, nanosec: 0}
      },
      pose: {
        position: {x: 0.0, y: 0.0, z: 0.0},
        orientation: {x: 0.0, y: 0.0, z: 0.0, w: 1.0}
      }
    },
    {
      header: {

        stamp: {sec: 0, nanosec: 0}
      },
      pose: {

        orientation: {x: 0.0, y: 0.0, z: 0.0, w: 1.0}
      }
    }
  ]
}"

and on the terminal i have

and i can actually see the path generated on rviz, but the camera doesnt moving there. And I wonder if there could be a parameter or something else that blocks it.

Thanks !

We are finding a way to solve this problem indeed. It’s caused by a wrong handling of the “carriage return” in the ROS 2 console log.

Concerning the new problem, it’s still not clear.
How are you moving the camera? Are you sending commands to ISAAC Sim?

I cannot understand the purpose of this command
ros2 topic pub /zed/zed_node/path_map nav_msgs/msg/Path [...]

[efesendil]

My goal is to move the camera around the room and perform mapping.
I was trying to send commands directly to the camera node—actually, I was trying to understand which message to publish to move the camera.
Should I have sent the commands to Isaac Sim by adding new components to my action graph?

[Myzhar]

@efesendil

The ZED Node does not have this feature.
You must move the camera in the simulator environment to see the camera move. The ZED SDK Localization module will process the information and track the movements and the ZED ROS2 Wrapper will update the TF and the pose and odom messages

@efesendil

Yes, exactly

[iamshakeelsindhu]

To continue with this thread (which is very helpful).

How about if I have ZEDX on my arm and it is moving, how do I get to do object detection (and merge the code with my robot arm’s to follow PICK N PLACE task)?
