Orientation of one coordinate system relative to another is defined by a sequence of three successive rotations. Yaw, pitch, and roll define one such sequence. There are multiple ways to define this sequence.
Yaw, pitch, and roll angles in Motion Analysis results are the sequence of
z,
-y, and
x-axis rotation angles measured about the rotating coordinate system, relative to the global coordinate system.
- Yaw
- The first angle of rotation in the yaw, pitch, and roll sequence. Yaw measures the rotation about the z-axis of the rotating coordinate system relative to the global coordinate system.
- Pitch
- The second angle of rotation in the yaw, pitch, and roll sequence. Pitch measures the rotation about the negative y-axis of the rotating coordinate system relative to the global coordinate system after the yaw rotation has been applied.
- Roll
- The third angle of rotation in the yaw, pitch, and roll sequence. Roll measures the rotation about the x-axis of the rotating coordinate system relative to the global coordinate system after the yaw and pitch rotations have been applied.
