COMPUTING DEVICE AND METHOD FOR IMAGE MEASUREMENT

摘要

A computing device measures an object using images of the object. The computing device processes the images to obtain a focus of a lens of the CNC machine. A second image of the object is captured at a focus of the lens of the CNC machine. The computing device obtains measurement points according to the second image. The computing device calculates a difference between determined coordinates of each measurement point and reference coordinates of a reference point corresponding to each measurement point.

1. A computing device comprising:
at least one processor; and a storage device that stores one or more programs, which when executed by the at least one processor, causes the at least one processor to: control a computerized numerical control (CNC) machine to move along a principle axis of the CNC machine; control a charge coupled device (CCD) to capture images of an object located at a platform of the CNC machine; obtain coordinates corresponding to each image during the movement of the CNC machine; process the images to obtain a focus of a lens of the CNC machine, and obtain a first image corresponding to the focus of the lens; control the CNC machine to move to the focus of the lens and control the CCD to capture a second image of the object; obtain measurement points according to the second image; simulate the measurement points to a geometrical element according to a predetermined type of an element using a predetermined algorithm; establish a coordinate system according to the geometrical element; determine coordinates of the measurement points in the coordinate system; and calculate a difference between the determined coordinates of each measurement point and reference coordinates of a reference point corresponding to each measurement point.
