Abstract: In a method of a computing device for calibrating light channels, one or more channel options of an illumination selecting unit of the computing device are selected to turn on the one or more light channels of a light source device. A camera unit captures a first image of the light source device. A zone and a serial number of each light channel are marked on the first image. Each channel option of the illumination selecting unit is eliminated. The camera unit captures a second image of the light source device when a light channel is turned off. The first image and the second image are compared, and a correlation between the light channel that is turned off and the eliminated channel option is determined. The serial numbers of the channel options are modified and remapped according to correlations between each light channel and each channel option.

Abstract: In a method for checking installation positions of probes of a star prober using a coordinate measurement device, the star prober is fixed vertically on a platform and supported by a movable arm, and a standard ball placed on the platform. The first probe measures a first point on a top surface of the standard ball, and the second probe measures a second point on the top surface of the standard ball. An X-Y coordinate system based on the first and second points is established, and a value of any deviation angle between the first probe and the second probe is calculated based on the X-Y coordinate system. The information is displayed for indicating whether the installations of the first and second probes are precise or not according to any deviation value, and the respective installations of the other individual probes are checked against the X-Y coordinate system.

Abstract: A measurement machine includes an optical lens and a spectral confocal sensor. An electronic device adjusts a zoom ratio of the lens to be a maximum ratio, and calculates X, Y, Z coordinate differences between the lens center and the sensor center. The electronic device calibrates the X, Y coordinate differences at least twice, to obtain calibrated X, Y coordinate differences. The X, Y differences are replaced by the calibrated X, Y coordinate differences when the calibrated X, Y coordinate differences satisfy first predetermined requirements. The electronic device further calibrates the Z coordinate difference at least twice to obtain a calibrated Z coordinate difference. The Z coordinate difference is replaced by the calibrated Z coordinate difference when the calibrated Z coordinate difference satisfies second predetermined requirements.
