Generation of detailed sky luminance maps via calibrated digital imaging

Abstract: Reliable prediction of daylight availability in indoor environments via computational simulation requires detailed and accurate sky luminance models. Sky luminance mapping via digital imaging can provide an alternative to high-end research-level sky scanners and thus support the provision of information on sky luminance distribution patterns on a more pervasive basis. In this paper, we compare variously calibrated sky luminance data derived from real-time digital sky images to photometric measurements. Subsequently we compare the application of a digitally derived sky model with other sky models toward the prediction of illuminance levels in a room.
