PROGRAM, METHOD, AND SYSTEM FOR DETECTING CRACK DEFECT GENERATED ON STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a program, system, and method for detecting crack defect of a structure.;SOLUTION: The crack-defect detecting program comprises processes (A1-A4) where a whole image data in which the entire prescribed range of a structure is photographed is orthogonally converted into a whole image data based on a focal length of a camera and a known dimension of the structure, processes (A5-A7) where a partial image data photographed by division and magnification from a position similar to that for entire photographing is collated with the whole image data or the orthogonally-converted whole image data, to acquire a positional relationship with each other, processes (A8-A10) a magnified image data which is sufficiently magnified and photographed to discriminate a crack defect is collated with the partial image data, so that the positional relationship between the photographing range for the magnified image data and that for the partial image data is acquired, and processes (B1-B8) where the magnified image data is used to discriminate the crack defect.;COPYRIGHT: (C)2003,JPO
