Hello @jhielson,

Thank you for writing to us. Could you please tell us on which version of ROS are you trying to test the code? Have you tested the same in a clean docker environment?

Thank you,

Best Regards,

Hi @saikishor,

Thanks for your prompt reply. I am using ros noetic without docker.

Hi @saikishor,

Which versions do you recommend for Ubuntu, ROS and OpenCV?

Hello @jhielson,

Which versions do you recommend for Ubuntu, ROS, and OpenCV?

Standard Ubuntu with ROS noetic should be fine. On noetic, it works with version 4.2.0.

We are unable to reproduce the issue. Could you give us more information on this?

Thank you,

Best Regards,

Hi,

I have been using Ubuntu 20.4, ROS noetic and OpenCV 4.7.0.
Do you recommend any docker image?

I tried to use the aruco package with my web_cam (http://wiki.ros.org/usb_cam) and kinect (http://wiki.ros.org/freenect_launch). But it did not work for both of them.

I can launch everything and see on rviz the camera's image.

But aruco_ros dies when I try to read the result topic:

I do not know how to solve this issue.

Best regards,

Hello @jhielson,

Unfortunately, We do not support different OpenCV versions other than the standard version that the ROS distros. I recommend you, use the standard version that ROS noetic uses. If it cannot be used in your case, I'm afraid you have to figure it out on your own.

Thank you,
