ABSTRACT:
A method for automatic focusing of images, which is typically used in image measuring. Key aspects of the method involve a step of controlling a moveable part to move within a predetermined focusing area, a step of processing consecutive images to obtain definition values of the consecutive images, and a step of calculating a focus location of the consecutive images. In particular, if it is the second time to focus the images, the method involves the step of calculating the focus location of the consecutive images.
