noetic process has died
Hello, may I ask why when I run single,launch file, call rqt to see the result will kill the process? I have checked the set parameters and there is no error. I ask for your help, thank you.
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, PAL Robotics Team
@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?
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] 【1713951282.914114320]: Inttlaltzing nodelet wtth 4 worker threads. [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:

hi I ran into the same problem with you, have you solved it? could you please tell me how to solve this one? you can reply me in Chinese as well
@chenglei11 I was able to implement it on another noetic version of the computer, but the code used was previous, that is, I'm not sure whether the author of the package changed the code to cause the conflict or the computer environment itself, so I guess if I can use the earlier version of the noetic package to try it?
@saikishor I'm sorry for not replying in time. I mean, when I select the topic result from the view-image option in the rqt visual interface, the program running single.launch will be killed, which means that we need to subscribe to the topic result when we recognize the QR code. No matter what the situation is, once we subscribe to the topic, The program will be killed.

yeah i can also implement it on another computer, have you tried this method? did it work?
