ABSTRACT:
A grinding method includes the steps of: enabling an image-capturing device to capture a set of consecutive images containing a workpiece being ground by a grinding device; enabling an image-processing device to identify the workpiece from the images, to detect a top edge of the identified workpiece from a latest one of the images, to locate a set of image pixels that lie on the top edge of the workpiece, and to determine relative heights of the image pixels; and enabling a controlling device to control grinding operation of the grinding device with reference to the relative heights of the image pixels. A system that performs the grinding method is also disclosed.
