Hello @wangqingyu985,
The ARuCo pose information is only published when there is a subscriber and it is the same for the TF. This is done to reduce the computational load on the CPU. If you are still facing the issue, we request you send the proper instructions to reproduce the issue. If not, it would be difficult for us to help you.

@saikishor
Thanks for your kindly and quickly reply. I found the issue you mensioned above when using RealSense D435 camera, and it is OK when I modified the following codes in simple_single.cpp for RealSense. But it is strange when I replaced the camera into ZED Mini, I can not get the aruco_marker tf information.
For RealSense camera, when I annotated the above code, I can finally get the tf information.

Hello @wangqingyu985,
Thank you for providing the proper information. Regarding your issue, it seems to me that the camera is not calibrated and the information inside the camera_info
topic might have zeros instead of some valid values.
Thank you,

Hello @wangqingyu985,
Could you please share the info from the camera_info
topic?

Sure, let me see......
I do not have GPU on my computer, so I used the zed ros wrapper for CPU, the link is: https://github.com/willdzeng/zed_cpu_ros
For launching the ZED camera, I use zed_cpu_ros.launch

Hello @wangqingyu985,
I'm not sure about the issue here, but I think it is from the camera_info topic because that is what it uses to compute the transformation.
Thank you,

It seems the hight and width are 0 in camera_info topic, what should I do to solve this problem?

Hello @wangqingyu985,
For using the aruco_ros, you need to have the intrinsics of your camera calibrated. I think you could fix it, by calibrating your camera. You can find some info here : http://wiki.ros.org/camera_calibration. Once you solve your issue, please respond here or close the issue.
