Automatic image acquisition processor and method
An automatic method for determining the geometric center of an element having a known peripheral shape of double symmetry is described which consists of: selecting a trial center of an image of the element and defining a plurality of sectors radiating from the trial center and encompassing all of at least a preselected portion of the element image; determining which ones of a locus of points overlie the image, the locus of points consisting of a number of spaced points along a line running through all of the sectors and having a predetermined relationship to the trial center; comparing the number of points that overlie the image in each sector with the number of points overlying the image in each of the other sectors; ascertaining whether the comparison is the same as a predefined comparison that exists when the trial center is the geometric center of the element; and if the comparison does not equal the predefined comparison, relatively moving the trial center with respect to the geometric center and repeating the selecting, determining, comparing and ascertaining steps.
