<P>PROBLEM TO BE SOLVED: To provide an algorithm for calculating crack width for a binary image of a crack obtained by carrying out a binarization processing after imaging the crack. <P>SOLUTION: Each segment of a piecewise segment arc along a crack and a band with equal width set so that the piecewise segment arc can be included, or that it can be made in parallel with the piecewise segment arc are prepared, and a crack width calculating method for globally calculating the width distribution of the crack for the arc length of the piecewise segment arc by calculating the area of the crack of the local region in the band is used several times to bands with the plurality of kinds of band width, and the calculation data of the global crack width are edited so that that global crack width distribution can be calculated. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
