Hello everyone I want to know how to use apriltag on absolute coordinates I see the website https://blog.csdn.net/TFZ941214/artic... here is seems to relative coordinates can anyone help? And I want to know in the website the tag_yaml the means about x y z?
The apriltag_ros gives you the relative coordinates from the camera to the apriltag. They are also given as tf-frame see tf-package. If you connect your camera-frame with your fixed frame (normaly world or map). You've got your absolut coordinates. The Z-axis is in the direction of the camera view. X and Y are the other both axis (up and the the right side). Hope I could help you.
