Hi I have frames issue. I installed ar_track_alvar package and I started gazebo. The AR tag has no movement in the scene. However in RVIZ, its frame ar_marker_9 moves. as shown in the following: Screenshot from 2021-03-09 16-25-05 Which lead to inaccurate measurements of the distance of the tag with respect to the camera frame . Which can be seen in the following image. Screenshot from 2021-03-09 16-24-29 Although, it should be close to the pose of the ground truth of the quadcopter since the tag is on the ground. (See this image) Screenshot from 2021-03-09 16-24-45 Please can someone tell me why the frame is moving while it should not move Thanks in advance and to get an accurate measurements what should I do

Hi again, I need the right size of the tag, because the pose changes each time I set different size. where can I find the exact size!!! because that will be important to get an estimate of the tag’s position with respect to the camera
