Claim 5:
6. The calibration apparatus in claim 4, wherein the tool calibration procedure comprises a tool dimension calibration procedure for obtaining a displacement amount of the TCP with respect to the flange and a tool direction calibration procedure for obtaining a rotation amount of the TCP with respect to the flange, and the processor is configured to establish the second homogeneous matrix based on the displacement amount and the rotation amount; wherein when the tool dimension calibration procedure is performed, the processor is configured to control the tool to make the TCP arrive at the same positioning point and block the light beam under multiple gestures, record coordinate information of the tool under each of the gestures respectively, and compute a dimension of the tool according to the coordinate information; wherein when the tool direction calibration procedure is performed, the processor is configured to control the tool to move and block the light beam based on multiple heights, compute a horizontal displacement amount of the flange for the tool to block the light beam upon each height, and compute a direction vector of the tool according to the multiple horizontal displacement amounts.
