Orientation

Yaw Pitch and Roll (Image source: Wikipedia)

Orientation represents the rotation of a marker around its center. These can be accessed as follows:

yaw - the angle of rotation in radians clockwise about the vertical axis.
pitch - the angle of rotation in radians upwards about the transverse axis.
roll - the angle of rotation in radians clockwise about the longitudinal axis.

markers = vision.detect_markers()

for marker in markers:
   print(marker.orientation.yaw)
   print(marker.orientation.pitch)
   print(marker.orientation.roll)

The following table visually explains what positive and negative rotations represent.
