Abstract
The length, area or the like of a portion of an object is measured for examination through the processes of first, displaying an image of the object on a monitor; second, after producing a simulating graphic form corresponding to the object, specifying certain positions of the object image on the monitor to which a plurality of positions of the simulating graphic form should correspond; third, varying the attitude of the simulating graphic form on the basis of data on the specified positions in such a manner that the simulating graphic form becomes substantially coincident with the object image; and fourth, causing a plurality of points forming the particular examination portion of the object to have their position on the object image specified so that, on the basis of data on the position of these points, corresponding points on the simulating graphic form are determined.
