| Abstract: | In the present paper the problem of calculation of a three-dimensional digit-al surface with the help of the digital image processing technique is discussed.The combination of the method of the product-moment correlation and that ofthe edge correlation is effective for colculation of all uncontinuous surface. In or-der to obtain more fine and reliable results the correlation method with multi-photographs is used. Finally, an example with the test photographs is given. |
