Claim 7:
8. The calibration apparatus in claim 7, wherein the processor is configured to execute the following actions to implement the three-point fix procedure:
controlling the TCP to arrive at a first positioning point on the two-dimensional plane and block the light beam;
recording coordinate information of the TCP on the first positioning point;
controlling the TCP to arrive at a second positioning point on the two-dimensional plane and block the light beam, wherein a height of the second positioning point is the same with a height of the first positioning point;
recording coordinate information of the TCP on the second positioning point;
controlling the TCP to arrive at a third positioning point on the two-dimensional plane, wherein a height of the third positioning point is different from the height of the first positioning point and the height of the second positioning point;
recording coordinate information of the TCP on the third positioning point; and
performing the three-point fix procedure according to the coordinate information of the first positioning point, the second positioning point, and the third positioning point.
