Title
(EN) Concrete Structure Crack Inspection Device and Crack Inspection Method
Abstract
(EN)

A crack inspection device (6) for a concrete structure (1) includes: storage means for storing raster data obtained by imaging a surface (2) of the concrete structure (1) having a crack (3); conversion means for performing raster vector conversion on the data obtained by digitizing the raster data; data superimposing means for superimposing the vector data of the crack (3) obtained by the conversion means on the graphic data of the surface (2) of the concrete structure (1) while matching the coordinates; and output means for outputting the superimposed data obtained by the data superimposing means.
