noetic process has died

Hello @Panda12580!

It is indeed weird that setting parameters through service works but not through the rqt reconfigure, at the end of the day, they are doing the same. We cannot see the screenshot you have attached. Could you reattach it?

Thank you

@saikishor Thank you for your reply. I have updated and uploaded the picture. Please check where my mistake is.

I set up the single.launch file and then start rs_camera.launch, but I want to see images via rqt and subscribed to aruco_ros/result ,
the background process will be killed as soon as I do this.

@Panda12580 I don't see the relation between rqt image viewer and the point you said about setting parameters through the command line. They are completely different.

What I recommend is to try to subscribe to the topic in the command line and see what would happen. This part is something that is tested, so I expect it to work without issues.

Thank you,

Best Regards,

@saikishor Hello, I have been using the aruco-ros package recently on the Ubuntu 20.04 system. When I run the following command:

bash
rosrun image_view image_view image:=/aruco_single/result
the single.launch node dies.

Can you let us know what happens if you subscribe through command line?

Can you let us know what happens if you subscribe through command line?

I opened three terminals and ran the driver node for the d435 camera, the single_realsense node for aruco_ros, and subscribed to aruco_single/result using the command line。

The terminal display for subscribing to aruco_single/result using the command line reads:
rosrun image_view image_viewer image:=/aruco_single/result

[INFO][1713951283.689522413]: Using transport "raw"

When I subscribe to the aruco_single/result topic, it shows the following in the terminal of aruco_ros:
