Abstract

There is a solar sensor used in vehicles to estimate thermal radiance source position (azimuth and elevation) in the sky hemisphere and the amplitude of irradiance. That data is used for adjusting climate control systems for maximum passengers comfort in vehicle cabin. Producers of such sensors face the absence of standard on what is the position of radiance source in the sky hemisphere. Furthermore, current means to measure radiance distribution are very expensive. An algorithm was proposed to estimate thermal radiance center position, by means of standard DSLR camera equipped with fish-eye lens. The algorithm was put under test by implementing series of experiments. Result samples of the thermal radiance center estimated by sensor and by proposed algorithm where presented. Ill. 8, bibl. 5 (in English; abstracts in English and Lithuanian).
