ABSTRACT:
The method of this invention includes the steps of positioning a reseau with grid marks on the object and sequentially illuminating the grid marks separate from the object and illuminating the object separate from the grid marks or in a manner that the grid marks are not visible with the object. The image of the grid mark positions, when illuminated, are digitized and stored in computer memory and correlated with the image of the object when it is illuminated and digitized. The scale of the image can also be correlated to the scale of the grid marks.
