Thermographic methodologies used in infrastructure inspection: A review data acquisition procedures

Abstract

InfraRed Thermography (IRT) is one of the best tools for the thermal characterization of the materials of structures and for the detection and thermal characterization of the most typical defects in the infrastructure field. An exhaustive review of the most recent thermographic acquisition (data collection) procedures in infrastructure inspection is presented here, comparing the existing variety of experimental thermographic configurations for infrastructure inspection. Furthermore, a discussion searching similarities and differences between data collection procedures, together with a series of objective and critical conclusions, are described
