摘要： PROBLEM TO BE SOLVED: To provide a crack investigation device, a crack investigation method and a crack investigation program capable of reducing investigation time and improving accuracy of the investigation.SOLUTION: The crack investigation device 1 is provided with an infrared sensor 31 for photographing a surface of a concrete structure and obtaining an infrared image in which temperature distribution on the surface is visible, a telescope 2 for visually recognizing the surface and a collimation adjustment means 22 for adjusting a focal point of a lens of the telescope. The collimation adjustment means 22 adjusts the focal point of the lens which constitutes an optical system 21, on the basis of the temperature distribution of the surface shown in the infrared image. Furthermore, features of the shape of a crack obtained from the past investigation result is utilized for future crack determination.
