In an electronic device, an image point A on an image of an object is selected. A spectral confocal sensor is controlled to move to a position above a measuring point A′ on the object, where the measuring point A′ corresponds to the image point A, and a Z-coordinate of the measuring point A′ is computed using the spectral confocal sensor. A focal position of the measuring point A′ is computed according to the Z-coordinate of the measuring point A′, and a CCD lens is controlled to move to the focal position. The Z-coordinate of the measuring point A′ is stored into a storage unit of the electronic device.

A measurement apparatus includes a lamp mount including a first mount and a second mount. The first mount has a first cavity to mount an observation module. The second mount has a second cavity to mount an image capture module. The measurement apparatus further includes a plurality of light modules mounted on an undersurface of the lamp mount. The second mount is disposed with an included angle relative to a first axis of the first cavity so that a second axis of the second cavity and the first axis converge on a point. The undersurface of the lamp mount is concave so that light from the light modules tilts toward the first axis, and the light and the first axis also converge on the point.

A scanner obtains point-cloud data of adjoining parts of a product. A computing device reads two point-clouds from the point-cloud data, fits two or more lines according to the two point-clouds, selects two lines that have the same ascending direction from the two or more lines, and creates a two-dimensional coordinates system base on the two selected lines. The computing device determines a highest point in each of the two point-clouds based on distances from each point in either of the point-clouds to a corresponding selected line, and determines two nearest points in the two point-clouds. A difference between Y coordinates of the two highest points is determined as a gap-height of two adjoining parts of the product, and a difference between X coordinates of the two nearest points is determined as a gap-width between two adjoining parts.

In a method for scanning edges of an object using a computing device, the computing device is connected to an image measuring machine including an image capturing device. A start point, an end point, a scan direction, and a scan distance interval are set. Scan points on the edges of the object are determined. For each scan point, the computing device aims the image capturing device at the scan point, controls the image capturing device to capture images of the object at different depths, and records focal points. Definition values of the images are calculated and an image with a highest definition value is determined. A focal point corresponds to the image with the highest definition value and so coordinates of the scan point are determined. Scanned edges of the object are formed based on all the scan points.

A system and method for automatically focusing an optical lens controls the light generated by a light-emitting device of an image measuring machine to penetrate a glass sheet, so as to project a picture of the glass sheet onto an object. The system and method further moves an optical lens along a Z-axis of the image measuring machine to capture one or more digital images of the object, and computes a definition value of each captured digital image. Furthermore, the system and method obtains a focus position corresponding to the highest definition value of the captured digital image.

A computing device connects with a vision measuring machine (VMS). Then the computing device generates a one time password (OTP). A size of the OTP, the OTP are stored in a predefined file. The computing device obtains a size of measurement program codes of the VMS. The size of the OTP and the size of the measurement program codes are stored in the predefined file. The measurement program codes are encrypted by the OTP. If the measurement data includes image data of an object which is measured by the VMS, the computing device stores the encrypted program codes, a type of the image data, image data, and a size of the image data in the predefined file.
