A Review of Illuminance Mapping Practices from HDR Images and Suggestions for Exterior Measurements
ABSTRACT High Dynamic Range (HDR) imaging has traditionally been used to create photorealistic images by combining multiple Low Dynamic Range (LDR) images. The application of HDR imaging has been since expanded to study the lighting environment by extraction of metrics such as luminance, illuminance, and glare. While luminance mapping of HDR images has been extensively studied in the recent past, research on illuminance mapping has been limited because of its strong dependency on surface materiality. This document reviews recent research on HDR techniques as it pertains to illuminance measurement and describes results of a pilot study comparing illuminance values captured and calculated using HDR against illuminance measurements collected with a calibrated illuminance meter, from a turf-based surface.
