Bridge Assessment Methods Using Image Processing and Infrared Thermography Technology
Identifying appropriate applications for technology to assess the health and safety of bridges is an important issue for bridge owners around the world. Traditionally, highway bridge conditions have been monitored through visual inspection methods with structural deficiencies being manually identified and classified by qualified engineers and inspectors. More advanced and objective bridge inspe...
متن کاملDetection of Subsurface Defects using Active Infrared Thermography
Active infrared thermography is a widely used technique in the field of nondestructive testing. The subsurface defects produce non-uniform heat dissipation and this phenomenon is captured by an infrared camera. The phase image gives a prominent description of the defects which are not visible in the captured image sequence. The effect of non-uniform heating and the variation in surface emissivi...
متن کاملDetection of rolling bearing degradation using infrared thermography
Our study deals with the quantification of the energy dissipated by a defect of spalling on the outside ring of a rolling bearing. A previous work showed a correlation between the thermal heating and the vibratory level generated by the progressive appearance of the defect. First, we propose a numerical model of the heat transfers In a second time, we developed an experimental setup. The result...
متن کاملSurface crack detection using infrared thermography and ultraviolet excitation
High signal to noise ratio is important within non-destructive testing. To achieve automatic inspection, including automatic evaluation, it is even more important. Infrared thermography is a suitable method for automatic inspection. One drawback with thermography of metallic structures is that due to shiny surfaces the reflectance is high and the signal to noise ratio will be low. This paper pr...
متن کاملDetection and characterization of buried landmines using infrared thermography
The application of infrared thermography to the detection and characterization of buried landmines (more generally, buried objects) is introduced. The problem is aimed at detecting the presence of objects buried under the ground and characterize them by estimating their thermal and geometrical properties using infrared measurements on the soil surface. Mathematically, this problem can be stated...
