Contribuciones al preprocesado, procesado y análisis en termografía infrarroja aplicados a ensayos no destructivos

Laburpena

The employment of measurement techniques using non-destructive testing with Infrared Thermography enables to evaluate and control all types of processes and materials, easily and without contact. For this reason, the overall objective of this thesis project is to make contributions to the knowledge of the different phases of the digital treatment of thermograms, as well as to the application to real problems and to the solution to the detected shortcomings. This process begins with the thermal imaging conditioning (preprocessing) as a previous step to the thermal imaging digital treatment (processing), where the identification of the material defects is improved, thus enabling its subsequent analysis and characterization (post-processing). The application fields of these contributions are varied: Welding evaluation and inspection processes, testing on composite materials for the aeronautics industry and the applications in Detection of pollutant in the environment and in Military textile industry.
