Concise exterior lighting simulation methodology

Abstract

A methodology is proposed which integrates advanced photogrammetric and computer-aided design (CAD) software with lighting simulation tools. The methodology consists of preparing a CAD model from digital photographs and then using lighting simulation packages to carry out the lighting analysis and produce a photo-realistic image. The latter can serve as a decision tool to the lighting designer. The methodology was specifically adapted for illumination studies of buildings of historical and/or architectural importance. The methodology was validated quantitatively by comparing simulation results with on-site field luminance measurements. The rendered photo-realistic images produced also compared favourably with photographs indicating the reliability and effectiveness of the overall simulation procedure.
