Figure 10.31 XOXY
The figure is xOxy type, the first point requires for the calibration is the origin of the coordinate system, the
second point is any point on the positive semi-axis of the X-axis, and the third point is formed at any point
within the first quadrant of the xOy plane. The angle formed by the three points is an acute angle.
Figure 10.32 XOXZ
The figure is xOxz type, the first point requires for the calibration is the origin of the coordinate system, the
second point is any point on the positive of the X-axis, and the third point is formed at any point within the
first quadrant of the xOz plane. The angle formed by the three points is an acute angle.
