Fractal study on infrared thermal-imaging

Infrared thermal imaging technology is one new method of the modern non-destructive testing. Expanding the qualitative analysis to quantitative characterization is hot and difficult of the infrared thermal imaging technology, that is to say, expanding assessing whether damage and judging injury location to structural integrity evaluation. The key lies in the extraction and description of the infrared thermal imaging characteristics parameters. This paper did fractal study on the experimental samples of infrared thermal imaging, including infrared thermal imaging graphics processing, fractal dimension calculation, realization of calculation program and gray, network and scale and so on, which is the foundation for further study on concrete structure damage and fracture or fracture criterion and the experimental calibration.
