In the soundness diagnosis of concrete structures, monitoring the width and extension of concrete cracks is important.
In the continuous monitoring of cracks, simplifying monitoring methods will lead to "sophistiaction of inspection work" and "reduction of additional investigation work" in inspection work.
Therefore, we propose a method for improving the accuracy of concrete cracks by simple measurement and a measurement method without individual differences by utilizing digital monitoring devices (for instance, digital microscope, 3D camera technology, infrared thermography camera, etc.)
