T I T L E METHOD AND APPARATUS OF DETERMINING THE CENTER OF AREA OR CENTROID OF A GEOMETRICAL AREA OF UNSPECIFIED SHAPE LYING IN A LARGE X-Y SCAN FIELD INVENTORS Harold F.L. Pinkney Charles Perratt ABSTRACT OF THE DISCLOSURE A method of obtaining on-line date useful in determining the center of area or centroid of a geometrical area of unspecified shape lying in a large x-y scan field and having its existence indicated by a level discriminated am- plitude or intensity or a parameter measurable in the z-dimen- sion comprising; scanning the x-y field in a known raster pattern and obtaining a series of discrete output voltage pulses related to elemental x-y points in the scan field and having an amplitude related to the amplitude or intensity of the said parameter; generating a series of discrete clock pulses related to elemental x-y points in the scan field; obtaining a series of x and y synchronizing pulses from and related to the x-y scan field; establishing in relation to the clock pulses and the x and y synchronizing pulses a smaller x-y scan field in the form of a rectangular window around the geometrical area in the larger x-y scan field, the boundaries as x-y co-ordinates of the said window being known; identifying, from the series discrete clock pulses, those pulses that coincide with pulse obtained above having an amplitude above a present voltage level and which fall within the bondaries of the smaller x-y scan field such as to define sample point areas in the geometrical area; making an overall count of the number of pulses identified above, making a count of the number of elemental x-y point each of the pulses identified above are spaced from a boundary of the window in both the x and y directions to provide x-moment arm counts and y-moment arm counts, and summing the x-moment arm counts and y-moment counts, said counts taken with the count obtained from above providing data for computing the center of area or other mathematical functions of the geometrical area.
