Abstract
A method for determining hardness of a material by implementing 3D imaging is proposed. The imaging provides database of points on the 3D imprint in an orthogonal X-Y-Z coordinate system. An imaginary image of the imprint is formed by finding a plurality of intersection points obtained by intersecting the imprint image in X-Y plane with the X-Z plane movable in the Y-axis direction for obtaining a plurality of points of intersection that lay in the X-Y plane. Statistical processing of the plurality of the points of intersection makes it possible to form imaginary image of the imprint in the X-Y plane and to use the reference dimension of the obtained imaginary image as a parameter for insertion into the hardness calculation formula.
