Fig. 2
Coordinate schematic diagram of dairy cow posture transitions Note: X n pointed to the east; Y n pointed to the north; Z n was vertical, pointing upward with respect to the horizontal plane. The body-fixed coordinate system was attached to the cow's neck, with X b pointing to the right of the body; Y b pointing forward; Z b pointing upward, perpendicular to the plane formed by X b and Y b. There are three posture angles, namely pitch angle ( θ), roll angle ( φ), and yaw angle ( ψ), which represent the orientation of the cow relative to the ground in the cow coordinate system.
