CRACK DETECTOR, CRACK CONTINUITY DETERMINATION SYSTEM, CRACK DETECTION METHOD AND CRACK DETECTION PROGRAM

MASUMOTO KAZUHIKO / NONAKA HAYATO / NAKAJIMA MAKOTO

To detect cracks promptly with a constant degree of precision.SOLUTION: A crack detector 100 includes: a sine waveform extraction part 22 which analyzes a development image that is created by photographing an inner wall of a bore hole 2 formed in foundation ground 1, and extracts a sine waveform from the development image on the basis of a crack; and a strike/inclination acquisition part 23 which acquires the strike and inclination of the crack, from the sine waveform.SELECTED DRAWING: Figure 4

【課題】迅速かつ一定の精度で亀裂を検出する。【解決手段】亀裂検出装置１００は、基礎地盤１に形成されたボアホール２の内壁を撮影して作成された展開画像を解析して、展開画像から亀裂に基づいて正弦波形を抽出する正弦波形抽出部２２と、正弦波形から、亀裂の走向及び傾斜を取得する走向傾斜取得部２３と、を備える。【選択図】図４
