Ros Node Dies after few seconds - ZED2 camera about ros_openpose HOT 8 CLOSED

Hi @AswinkarthikeyenAK

It is difficult to say what is wrong here. Unfortunately, I don't own a ZED2 camera. So I can not debug your issue exactly.

However, looking into your master.log file, this is what I found-

[rosmaster.master][INFO] 2020-09-29 10:57:57,299: publisherUpdate[/tf_static] -> http://lams-desktop:33065/ ['http://lams-desktop:37247/']: sec=0.00, exception=<Fault -1: 'publisherUpdate: unknown method name'>

This is what causing the ROS node to shutdown. I am sorry, you need to debug from here. Please let me know the progress and your fix for it.

Thank you very much for your kind understanding.

Hi @ravijo
I had initially managed to fix the issue and everything seemed to work fine.
But since couple of days back I am not getting proper 3d points in Rviz.
Please find the image attached.
@ruksen25, Do you think you can help me out here if possible,please?
Really appreciate your assistance
I have checked and made sure I made the necessary changes to the ZED Ros_wrapper and changed this
openni_depth_mode: true # 'false': 32bit float meters, 'true': 16bit uchar millimeters

Thanks

Hi @AswinkarthikeyenAK

I am glad to hear from you.

I had initially managed to fix the issue and everything seemed to work fine.

Can you please tell us what the problem was? It will help us to understand the issue properly.

But since couple of days back I am not getting proper 3d points in Rviz.

Do you mean that earlier, you were getting correct a 3D view? It is difficult to understand the issue right now. You should better tell us more.

Right now, I see that the actual scene is hidden behind a green color object. I suspect that this green color is coming from ros_openpose. Can you please decrement the values of the following variables-

• skeleton_line_width in run.launch
• id_text_size in run.launch

It would help if you also gave it a try by upsetting the skeleton flag in run.launch

@vipulgarg1998:

It is always suggested to share detailed information about the issue. Moreover, we do not face such an issue in our dev machine.

Kindly reinstall and comment back if the problem persists.
