| Popis: | Póster presentado al 34th Solar World Congress (SWC). Santiago (Chile), 2019. The characterization of sky conditions according to the CIE Standard General Sky classification requires knowledge of diffuse luminance angular distribution in the sky vault. This variable is usually measured by sky scanners. However, commercial sky scanners have different drawbacks related to their resolution and measurement time. An alternative to these devices is the use of sky images captured with a digital camera equipped with a fisheye lens. The range of luminances that may occur in the sky makes it necessary to use high dynamic range (HDR) images obtained by the fusion of a series of low dynamic range (LDR) images. Two procedures for the characterization of sky conditions according to the CIE standard using HDR images have been applied and evaluated. This work has been performed as a part of Project RECHICRAL (0011-1365-2017-000168), co-financed by the Government of Navarre and the European Regional Development Fund through the FEDER Operational Program 2014-2020 of Navarre, and Project IRILURREFLEX (ENE2017-86974-R), financed by the Spanish State Research Agency (Agencia Estatal de Investigación, AEI) and European Regional Development Fund (Fondo Europeo de Desarrollo Regional, FEDER). |
