5 Take the x and y values from p_centre and enter them into the base frame
values for the conveyor, converting to meters, see Application
manual - Conveyor tracking. The z value will be entered later, once the work
object zero position has been chosen.
Calculating the quaternion
Use this procedure to calculate the quaternion for the base frame orientation.

1 With the recorded angle in step 5 when calculating the x and y positions for
the base frame. This is angle , see example measurement points in
Defining the base frame orientation and start window start calibration on
page 213.

Calculate P from the XP1 and YP1 coordinates of P0 and the atan function.
If the point is at first quartile or frouth quartile: Pθ = arctan(YP1/XP1)
