Error - "process has died" #15
Comments
Hi, Start it with gdb, "run", then when it crashes execute "bt", and post the output here. Also: what operating system, which ROS are you running on? |
You could also start off executing the node with the output visible, just modify (or even better, make a new launch file based on the single.launch) the line: https://github.com/pal-robotics/aruco_ros/blob/master/aruco_ros/launch/single.launch#L10 and add output="screen" So it will look like: So at least you'll get the prints of the node before dieing. |
By default the node is subscribing to /stereo/left/camera_info and /stereo/left/image_rect_color. You should modify the single.launch file and remap the /image and /camera_info topics to the corresponding topics of your camera. |
I think I have ran into the issue today. Could you please confirm that the camera_info has D: [] ? rostopic echo /your_camera/camera_info |
Hi, Sorry for no answering, I was very busy and I had to do a lot of things. I have tried many of the things that you told me to do (for example I had to remap the /image and /camera_info topics to my camera's topics), but I couldn't solve the problem. |
I beleive I solved the problem that caused this crash. For now it is gone, the solution is not the best but lately I've been working on rearranging some code so it will get prettier. |
Hello,

Hello @Aya-nuomi, This issue had been closed for a long time. If you are facing any issue, please open a new issue and specify the detailed steps to reproduce it, and also provide us the data of the camera info you are using. Thank you, Best Regards, |
Hello,
Thanks for sharing this package. I am traying to work with Aruco and ROS and I have though that this package could be useful for me.
The problem is that I get the following error when I try to run the single.launch file:
laboratorio@ai2-labmix7:~/catkin_ws/src/aruco_ros/aruco_ros/launch$ roslaunch single.launch
... logging to /home/laboratorio/.ros/log/b49e99ec-fa18-11e4-895a-4c72b9b133b4/roslaunch-ai2-labmix7-13054.log

I don't know how to solve this problem, so if anyone could help me it would be great.
Thank you.
