The thermography as a methodology to quantitative data acquisition is not usually addressed in the degrees of university programs. The present manuscript proposes a novel approach for the acquisition of advanced competences in engineering courses associated with the use of thermographic images via free/open-source software solutions. This strategy is established from a research based on the statistical and three-dimensional visualization techniques over thermographic imagery to improve the interpretation and comprehension of the different sources of error affecting the measurements and, thereby, the conclusions and analysis arising from them. The novelty is focused on the detection of non-normalities in thermographic images, which is illustrates in the experimental section. Additionally, the specific workflow for the generation of learning material related with this aim is raised for asynchronous and e-learning programs. These virtual materials can be easily deployed in an institutional learning management system, allowing the students to work with the models by means of free/open-source solutions easily. Subsequently, the present approach will give new tools to improve the application of professional techniques, will improve the students’ critical sense to know how to interpret the uncertainties in thermography using a single thermographic image, therefore they will be better prepared to face future challenges with more critical thinking.

“…La inspección termográfica de envolventes de edificios se suele realizar sin utilizar ningún medio de excitación externo, es de-cir, estudiando su propio patrón de emisión infrarroja en estado normal. Por ello, estas inspecciones se enmarcan en el campo de la termografía pasiva, en contraste con la termografía activa, en la que se aplica una excitación térmica artificial con el objetivo de inducir una excitación de los electrones de los átomos del material y el consecuente incremento de la emisión en forma de radiación infrarroja [22]. Las principales metodologías para obtener termografías de un área de interés son [23]: reconocimientos aéreos, vuelos automatizados, muestreos de pasada continua a pie de calle, muestreo a pie tradicional (externo; externo e interno), muestreos con repetición y muestreos time-lapse.…”

This paper presents the integration of data acquisition from land and unmanned aerial vehicles (mUAV) in the visible and thermal channels, validating the results for inspection and detection of different pathologies on facades of real case studies. An original methodology is proposed and tested for rapid inspection of building envelopes, supported by geospatial techniques. Frequent pathologies, as moisture damages and thermal losses are analyzed in real urban facades. UAV-based inspection allows checking inaccessible areas with visible and thermal sensors, obtaining homogeneous global models that can be analyzed with sufficient time and detail at the office (postprocessing). Based on these models, objective diagnosis can be performed even in the most complex neighborhoods and building designs, as well as energy balance analyses and detection of pathologies with economical and reliable means for large areas. This technology is ready for use in building inspection and it is very useful in the design of rehabilitation projects for tall and complex buildings in the framework of energy efficiency.

The present article proposes a workflow based on free/open-source software solutions for the acquisition of competences in engineering courses related to the use of thermographic images. The approach is aimed to three-dimensional visualization techniques over thermographic images to improve the comprehension and interpretation of the different error sources that affects the measurements, and therefore the conclusions and analysis derived from them. The present work is framed inside the virtual laboratories discipline, as the new learning material can be employed for the acquisition of competences and skills. Additionally, it can be used for the evaluation of competences in asynchronous and e-learning programs. The learning materials could be easily deployed in a learning management system, allowing the students to work with the models by means of opensource solutions easily, both in asynchronous and face-to-face courses. Consequently, the present approach will improve the application of professional techniques, so the future professionals will reach the working market better prepared.
