El uso de la termografía infrarroja com
o técnica sobradamente provada para la inspección de edificios y localización de patologías como fugas de aire, humedades, etc. Nos permite realizar un examen visual “in-situ” de calidad de los objetos de estudio gracias a la posibilidad de visualizar en tiempo real los resultados pudiendo detectar sin dificultad los desperfectos o elementos característicos de estos. Estas técnicas de medición cualitativa nos proporcionan la posibilidad de realizar inspecciones rápidas y eficaces sin contacto directo con el objeto y de forma no destructiva, lo que disminuye tanto el riesgo de incidentes para los operarios como los daños producidos en los propios objetos de estudio ocasionados por otras técnicas intrusivas. Además, también se ha demostrado la utilidad de la termografía infrarroja como técnica puramente de medida a través de su utilización para el cálculo de propiedades termofísicas de materiales tales como difusividad y transmitancia térmica.
En el caso de termografía cualitativa, las publicaciones existentes tratan de estudios realizados in-situ, principalmente en edificios históricos o elementos del patrimonio cultural, mientras que los estudios cualitativos se realizan, en la mayor parte de los casos, en laboratorios sobre muestras de tamaño limitado. En aquellos casos en los que se han realizado estudios termográficos cuantitativos sobre edificios in-situ, los valores de temperatura son empleados con el objetivo de obtener propiedades termofísicas (conductancia térmica) reales del cerramiento, sin embargo su distribución espacial no es considerada.
Conjugar ambas aplicaciones permitirá la automatización del cálculo de pérdidas de calor a partir de las temperaturas medidas con una cámara termográfica. De este modo, no solo se usa la termografía para representar el estado de la pared, sino que también se usan los valores de temperatura contenidos en la termografía para la extracción de parámetros métricos del edificio en estudio, por lo que la hibridación de la información termográfica con el material cartográfico de precisión permitiría extraer la geometría real del objeto de estudio con textura termográfica, pudiendo así realizar mediciones precisas de los elementos de interés directamente sobre el resultado obtenido.
Estudios como el publicado por EuroACE en 2010 colocan la mejora de la eficiencia energética en edificación en cabeza de las acciones necesarias para la reducción de emisiones de gases del efecto invernadero y gasto energético, así como para servir de empuje a la generación de empleo. Especial es el caso del parque de edificios ya construidos, la mayoría procedente de los años 1940-80, con normativa inexistente y recursos escasos. En ellos las obras de rehabilitación energética pueden suponer un ahorro de hasta el 75% en consumo de energía. En España existen 13 millones de viviendas susceptibles de intervención, cuya rehabilitación energética supondría una reducción de las emisiones del sector del 34% con respecto al año 2001.

The use of infrared thermography as a widely tested technique for building inspection and location of pathologies such as air leakage and moisture allows the performance of quality “in-situ” visual examination of the objects under study due to the possibility of obtaining real-time results, being able to detect without difficulty damages or material characteristics. This qualitative measurement technique provides the capability of doing quick, effective and non-destructive inspection without direct contact with the object under study, decreasing the risk of incidents to operators and the damage of the objects comparing with other intrusive techniques. Furthermore, the utility of infrared thermography as a measurement technique has been proved by its use for the determination of the thermophysical properties of materials such as diffusivity and thermal transmittance.
In the qualitative approach, some authors have performed in-situ studies, mainly in historical buildings or cultural heritage elements, whereas quantitative studies are performed mainly in laboratories with limited size samples. In those cases where quantitative thermography studies were performed in-situ, temperature values were employed in order to obtain the real thermophysical properties (thermal conductance) of the building envelope, but their spatial distribution is not considered.
Combine both applications will enable the automation of the heat loss computation from the measured temperatures with a thermographic camera. Thus, the thermography is not only used to represent the state of the wall, but also temperature values represented on the thermography for extracting the metric parameters of the study object so the hybridization of the thermographic information with precise cartographic material would allow to extract the actual geometry of the object of study with thermal texture, being able to make accurate measurements of the elements of interest directly on the obtained results.
Studies such as the one published by EuroACE in 2010, places improved energy efficiency in building construction at the top of the list of actions that need to be taken to reduce greenhouse gases and energy costs, in addition to acting as a stimulus to generate employment. In particular is the case of existing buildings stock, most of which dates back to the period 1940-80, constructed using non-existent standards and scarce resources. Here, energy refurbishment works could represent a saving of up to 75% in energy consumption. In Spain there are 13 million homes that could be the subject of intervention, where energy refurbishment could result in a reduction in sector emissions of 34% compared to 2001.

In urbanized Western Europe trees are considered an important component of the built-up environment. This also means that there is an increasing demand for tree inventories. Laser mobile mapping systems provide an efficient and accurate way to sample the 3D road surrounding including notable roadside trees. In this research line, a processing chain aiming at the extraction of tree locations and tree sizes from laser mobile mapping data is reached.
Such steps, in combination with code optimization are expected to be sufficient to reach the final goal of automatized estimation of features sampled by mobile mapping at a rate that matches the acquisition speed and at a quality that matches the result of a human operator.

Equipar drones con sensores láser, detectores de obstáculos y sistemas de control remoto permite obtener de forma segura y fiable los modelos tridimensionales de escenarios críticos, entendiendo como escenarios críticos todos aquellos escenarios en los que una persona correría peligro realizando los trabajos.
Este tipo de escenarios abarcan desde grutas angostas y estrechas a las que es difícil acceder, hasta escenarios industriales complejos, como subestaciones eléctricas, en las que existen riesgos de descargas eléctricas, salas de calderas, edificios con problemas estructurales etc.
A pesar de ser lugares críticos, su mantenimiento e inspección es un aspecto clave en el campo del control preventivo de averías y deformaciones, por lo que obtener el modelo tridimensional de estos lugares es fundamental. En este sentido, los drones terrestres, cada vez más sofisticados, permiten integrar escáner láser terrestre para capturar el entorno, asi como detectores de obstáculos y diferentes sistemas de comunicación, de modo que pueden moverse de forma autónoma o ser teledirigidos de forma remota.
Hasta el momento se ha investigado la integración de drones terrestres y escáner láser utilizando dos metodologías de trabajo diferentes, según el grado de precisión y detalle que se necesite y dependiendo de las dimensiones del espacio en el que se esté trabajando.
Finalmente, se está investigando la manera de combinar los modelos tridimensionales obtenidos por los drones terrestres con datos procedentes de drones aéreos equipados con cámaras fotográficas o cámaras termográficas. Combinar ambos modelos es esencial para obtener una cobertura total de la escena de estudio y poder detectar anomalías en cualquier lugar. Ésta línea de acción se está introduciendo para controlar subestaciones eléctricas y plantas solares fotovoltaicas ya que en ambos casos es posible detectar zonas con un calentamiento anormal que indiquen un funcionamiento que deberá revisarse.
Land drones can be armed with different devices such as terrestrial laser scanner, obstacle detectors or remote control systems, in order to provide accurate 3D models of unattended or critical environments in a safe way.
Environments like narrow caves that are difficult to access, electrical substations where there are risk of electric shock, boiler rooms or buildings with structural problems are considered critical environments for human operators due to the danger they entail.
Despite being critical spaces, its maintenance, inspection and control are essential to prevent damages and detect breakdowns, so accurate three-dimensional models are indispensable. For this purpose, terrestrial drones allow the integration of terrestrial laser scanners to capture the environment, as well as obstacle detectors and different communication systems, so that they can be autonomous vehicles or remote-controlled vehicles.
Depending on the accuracy needed and the dimensions of the study case, two different combinations of technologies have been explored, both combining laser scanner with land drones.
To complete this research line, we are working in different methodologies to combine 3D models obtained with land drones and data obtained with aerial drones equipped with conventional cameras or thermo graphic cameras.
Mix both kind of models make the three-dimensional model much more complete and it is possible to detect pathologies in almost everywhere. Some of this process has been used with success in electrical substations and photovoltaic solar plants, detecting, for example, anomalies in some panels.

Throughout history wolves and humans have had a conflictive and complex love-hate relationship. On one hand, wolves are frequently the culprits of livestock predation, creating tension with local farmers and landowners, while on the other, their domestic relative the dog is considered a cultural extension of the family. Due to the attacks produced on livestock, tension has formed over the years among rural populations. Unfortunately, Castilla y León is one of the country’s most affected areas by wolf attacks on livestock; with Ávila being a focal point for most of these damages. 
The objectives of this line of research are to use artificially intelligent algorithms to model and study the impact of wolves in the province of Ávila. Using spatial data, statistical Geographical Information System (GIS) approaches and Machine/Deep Learning, we hope to provide a new perspective to the study of wolf activities and attacks on local livestock. 
The advantages of artificially intelligent algorithms are multiple. These algorithms provide a new means of predicting when and where the next attack is most likely to occur. Likewise, additional research may be able to highlight which animals are more likely to be attacked. This data could be of great benefit to local agricultural communities, thus helping protect their assets and help alleviate tension that could better protect the wolf from danger of extinction.
A lo largo de la historia los humanos y los lobos han tenido una relación de amor-odio bastante compleja y conflictiva. Por un lado, en muchas ocasiones los lobos son los culpables de los daños o ataques al ganado, generando tensión con ganaderos y terratenientes, mientras que por otro lado el perro, su pariente domesticado, es considerado culturalmente como un miembro más de la familia. Debido a los ataques al ganado, con el paso de los años se han ido acrecentando las tensiones con las poblaciones rurales. Por desgracia, la Comunidad Autónoma de Castilla y León es una de las zonas del país más afectadas por ataques de lobo, siendo Ávila uno de los focos que más daños acumula. Los objetivos de esta línea de investigación es emplear algoritmos de inteligencia artificial para modelar y estudiar el impacto del lobo en la provincia de Ávila. Utilizando datos espaciales, enfoques estadísticos de Sistemas de Información Geográfica (SIG) y algoritmos de aprendizaje computacional, esperamos poder presentar una nueva perspectiva para el estudio de las actividades de los lobos y sus ataques al ganado local en la península. Las ventajas que presenta la inteligencia artificial son múltiples. Estos algoritmos son capaces de predecir con alta precisión dónde y cuándo es más probable que se produzca un nuevo ataque. De la misma forma, la investigación adicional puede destacar cual es el tipo de ganado más propenso a ser atacado. Estos datos pueden beneficiar a las comunidades ganaderas locales, ayudando a proteger a sus animales y a aliviar las tensiones generadas por los ataques, lo que puede a su vez ayudar a proteger mejor al lobo de su extinción.
