Claim 2:
3. The calibration apparatus in claim 2, 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 alignment device to perform an image analysis to the tool, control the tool to make the TCP arrive at the same positioning point in the three-dimensional space under multiple gestures based on data obtained from the image analysis, record coordinate information of the tool under each of the gestures, 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 in the three-dimensional space based on multiple heights and angles, and perform the image analysis to the tool by the alignment device to obtain positions and tilted angles of the tool for computing a direction vector of the tool.
