To provide a diagnostic system capable of easily detecting and specifying the presence or the absence, the location, and the size of defective parts of a structure, such as cracks and floating.
The infrared structure-diagnosis system is provided with an imaging part 1, having a digital camera 10 for imaging a visible image of the structure to be diagnosed, an infrared camera 11 for imaging the thermal image of the structure, and a laser range finder 12 for measuring the distances between the digital camera 10, the infrared camera 11, and the structure; a pan and tilt universal head 2 for swinging the fields of view of the digital camera 10 and the infrared camera 11 in the horizontal and vertical directions; and a processing unit 5 for performing various processings on the images imaged by the imaging part 1. The processing unit 5 corrects the visible image and thermal image of the structure from the imaging part 1, on the basis of the distances measured by the laser range finder 12 and the swing angles of the pan and tilt universal head 2.
