A method has been developed to reduce the volume of data required for an automated inspection systems. An inspection system determines whether the size of an object is within a predetermined range by scanning the object and comparing the results to data representing the desired size of the object. Referring to the drawing, for an object 10 being inspected prior systems assigned a nominal value (represented by area 12) for the object size which was approximately in the middle of the allowable size range, then scanned the object 10 to detect whether it was greater than the minimum and less than the maximum allowable sizes. For a given inspection field this resulted in "don't care" data represented by areas 14 which is not required for scanning but which must be stored along with the nominal size data.
