CREATTION OF CRACK DETECTOR ON REVETMENTS AND MEASURING CRACK USING ORTHOPHOTO

Abstract

Current maintenance methods of revetments are inefficient because it depends on the visual inspection of civil engineers. Thus, it is necessary to develop a quantitative and rational inspection method.

In previous studies, the authors developed a crack detector using CNN. However, in order to utilize detecting results in the current maintenance standards, crack width must be measured in actual size. Therefore, this study considered a method for measuring cracks from detecting results. As a result, the method is developed that can measure width of the entire crack.
