Title
(EN) CRACK INSPECTION DEVICE AND METHOD OF CONCRETE STRUCTURE
(JA) コンクリート構造物のクラック検査装置及びクラック検査方法
Abstract
(EN)

PROBLEM TO BE SOLVED: To perform a three-dimensional expression and its strength analysis of an internal structure of a concrete structure having a crack, by accurately expressing a position and a shape of the crack generated on the surface of the concrete structure by a further less data quantity.

SOLUTION: This crack inspection device 6 of the concrete structure 1 has a storage means for storing raster data provided by imaging the surface 2 of the concrete structure 1 having the crack 3, a converting means for performing raster vector converting processing to data provided by binarizing its raster data, a data superposing means for superposing vector data on the crack 3 provided by this converting means by adjusting coordinates to figure data on the surface 2 of the concrete structure 1, and an output means for outputting the superposed data provided by this data superposing means.
