CRACK DETECTION METHOD, CRACK DETECTION PROGRAM AND CRACK DETECTION SYSTEM
To provide a crack detection method, a crack detection program and a crack detection system which detect a crack occurrence state of concrete in a shorter time with higher accuracy in comparison to a conventional technique.SOLUTION: A crack detection method comprises: a crack occurrence region extraction step S11 of extracting a crack occurrence region by analyzing an analysis target region image BRG; a crack binarized image creation step S12 of analyzing the crack occurrence region in detail, binarizing the crack occurrence region in an analysis target region image BRG and creating a crack binarized image H2G discriminating between a crack portion and a non-crack portion; a crack element information creation step S13 of creating crack element information HYJ by dividing the crack portion in the crack binarized image into a plurality of crack elements that do not have a branch point; and a crack related information creation step S14 of creating and outputting crack related information HKJ including a crack damage feature amount on the basis of the crack element information HYJ.SELECTED DRAWING: Figure 2
【課題】コンクリートのひび割れ発生状況を、従来よりも短い時間で、且つ,、高い精度で検出するひび割れ検出方法、ひび割れ検出プログラム及びひび割れ検出システムを提供する。【解決手段】ひび割れ検出方法は、分析対象領域画像ＢＲＧを分析してひび割れ発生領域を抽出するひび割れ発生領域抽出ステップＳ１１と、ひび割れ発生領域を詳細に分析し、分析対象領域画像BRGの中のひび割れ発生領域を二値化して、ひび割れ部及びひび割れ部に区別したひび割れ二値化画像Ｈ２Ｇを作成するひび割れ二値化画像作成ステップＳ１２と、ひび割れ二値化画像中のひび割れ部を、分岐点を有しない複数のひび割れ要素に区分し、ひび割れ要素情報ＨＹＪを作成するひび割れ要素情報作成ステップＳ１３と、ひび割れ要素情報ＨＹＪを基に、ひび割れ損傷特徴量を含むひび割れ関連情報ＨＫＪを作成し、出力するひび割れ関連情報作成ステップＳ１４と、を備える。【選択図】図２
