Title: Method of inspecting mortar sprayed slope
Inventor: KOMIYAMA TAKAHITO
IPC: G01N25/72
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To safely, quickly and precisely detect the abnormal part of a slope by composing the infrared thermal image of a spraying slope with the visual digital image of the slope into one image after quantitatively grasping the surface temperature behavior of the slope. SOLUTION: An object surface is first two-dimensionally scanned by use of an infrared sensor to take the thermal image of the surface temperature distribution of the object, and a non-steady heat transfer analyzing system using finite element method is then constructed to quantitatively grasp the surface temperature behavior of a spraying slope. The visual digital steel picture of the spraying slope is also taken by use of a high performance digital steel, camera. Each of the resulting images is corrected in distortion by geometric correction, and composed into one image by the patchwork of a computer. The abnormal part of the thermal image is displayed with emphasis by photographing the same slope twice in the daytime and the night, and imaging the temperature difference between the two images. Thereafter, the infrared thermal image and the visual digital picture are composed into one image by the computer. Thus, the position, form and area of the abnormal part of the spraying surface can be precisely judged.
