La presente invención es un dispositivo (20) que comprende una cúpula (1) que a su vez comprende una estructura de baja emisividad y una pluralidad de sensores de radiación infrarroja (2) que convierten radiación infrarroja en temperatura, una base rígida (11) vinculada con la cúpula (1), que en su parte externa lateral comprende una banda cilíndrica (13) de alta emisividad y codificada mediante signos (14) de baja emisividad. Adicionalmente, el dispositivo (20) comprende un sistema de posicionamiento angular (4) emplazado en el interior de la cúpula (1), y una unidad de control (5) vinculada con el sistema de posicionamiento angular (4) y con los sensores de radiación infrarroja (2) para caracterizar los reflejos en el espectro infrarrojo térmico.Device for the characterization of reflections in the thermal infrared spectrum. The present invention is a device (20) comprising a dome (1) which in turn comprises a low-emissivity structure and a plurality of infrared radiation sensors (2) that convert infrared radiation into temperature, a rigid base (11) linked to the dome (1), which on its external side comprises a cylindrical band (13) of high emissivity and coded by signs (14) of low emissivity. Additionally, the device (20) comprises an angular positioning system (4) located inside the dome (1), and a control unit (5) linked to the angular positioning system (4) and with the sensors of infrared radiation (2) to characterize reflections in the thermal infrared spectrum.
Description
el sistema dentro de la escena termográfica de una forma no-invasiva, ya que no requiere de contacto con el objeto de estudio para proveer de resultados y es seguro, ya que es pasivo y no emite radiación peligrosa para los usuarios. the system within the thermographic scene in a non-invasive way, since it does not require contact with the object of study to provide results and is safe, since it is passive and does not emit dangerous radiation to users.

La presente invención es un dispositivo (20) para la caracterización y la eliminación de reflejos en el espectro infrarrojo térmico, que comprende, tal y como se muestran en la figura 1, una cúpula (1) que a su vez comprende una estructura espacial tipo “domo geodésico” de frecuencia 2 cuya superficie está recubierta de un material de baja The present invention is a device (20) for the characterization and elimination of reflections in the thermal infrared spectrum, comprising, as shown in Figure 1, a dome (1) which in turn comprises a spatial structure type “Geodesic dome” of frequency 2 whose surface is covered with a low material

posicionados en cinco localizaciones equi-angularmente distantes alrededor de la banda cilíndrica (13), en donde cada elemento comprende un cuerpo metálico de baja emisividad, para facilitar su detección e identificación por contraste con respecto a la banda (13). El número de elementos y su disposición permite que desde cualquier punto 5 de vista se localicen al menos 2 de ellos, lo cual, junto con la disposición que generen las señales de posicionamiento del propio sistema (4), permite obtener, por cotejo de ambas fuentes de datos (posicionamiento en la escena y señales de posicionamiento del sistema), la cuantía real del giro propio de la cúpula (1) (o giro respecto a su eje) y poder así localizar con precisión la posición relativa de la cúpula (1) con respecto al sensor positioned in five equi-angularly distant locations around the cylindrical band (13), where each element comprises a metal body of low emissivity, to facilitate its detection and identification by contrast with respect to the band (13). The number of elements and their arrangement allows at least 2 of them to be located from any point of view, which, together with the arrangement generated by the positioning signals of the system itself (4), allows obtaining, by comparison of both data sources (scene positioning and system positioning signals), the actual amount of the dome's own turn (1) (or turn relative to its axis) and thus be able to accurately locate the relative position of the dome (1 ) with respect to the sensor
10 termográfico que realice la captura de la escena. 10 thermographic that captures the scene.
De este modo y gracias a la geometría semiesférica de la cúpula, la banda de posicionamiento (13) y el sistema de posicionamiento angular (4), el dispositivo (20) se puede referenciar angularmente el vector asociado a la reflexión espuria de forma pasiva. In this way and thanks to the hemispherical geometry of the dome, the positioning band (13) and the angular positioning system (4), the device (20) can be angularly referenced the vector associated with spurious reflection passively.
