Hi Thien
Thank you for your reply . In order to set the calibration data I followed your instructions at Precision Landing with ROS, Realsense T265 Camera and AprilTag 3 - Part 2⁄2.
I have almost setup my non-GPS flight drone, and I am looking for a safe indoor location to try it
Thank you guys , I am really grateful for your help and hope to contribute when I will gain experience.
Regards
gian
