Hello @Yaoxingtian,

Thank you so much for your interest in the package. The estimation of ARuCo is based on the camera info topic, without having this info it is not possible to estimate the pose of the marker. That's why, if your camera is well calibrated, it will be reflected in the camera_info; hence, you have a better estimation.

We hope this answers your question.

Thank you,

Best Regards, PAL Robotics Team.
