Hello @Yaoxingtian!

Thanks for writing to us. Regarding your issue, I suggest using a rectified image in this case, and adding some filters to the pose would also help. You can also use 2 ArUco markers to distinguish the orientation. I hope this helps.

Thank you,

Best Regards,

and what do you think the valid Camera Resolution for stably detection？
