Abstract:
1. An image measuring machine, comprising: a star probe comprising a plurality of probe heads; a camera lens and a storage device; at least one processor; and a probe calibration system stored in the storage device and executed by the at least one processor, the probe calibration system comprising: a probe configuration module that configures probe configuration information for the star probe using a probe configuration file stored in the storage device; a probe calibration module that determines whether each of the probe heads needs to be calibrated according to the probe configuration information of the star probe, selects one of the probe heads to be calibrated from the star probe and calibrates a radius value of the selected probe head, determines whether there is a deviation between a center point of the selected probe head and a focus of the camera lens, calibrates the deviation between the center point of the selected probe head and the focus of the camera lens, and generates probe calibration information according to the calibrated radius value and the selected deviation; and a model display module that generates a star probe model for the star probe according to the probe configuration information and the probe calibration information, and displays the star probe model on a display device of the image measuring machine.
