Paper Abstract

Starting from three aspects, the paper introduces the reason and effects of glare and displays a kind of Unified Glare Rating(UGR) measuring system. Our research is dependent on the standard made by CIE and the UGR formula put forward by Sorensen, make use of digital camera, programming and digital image processing and develop a set of UGR measuring system. After testing, we find it able to measure indoor UGR and get repeatable results, which are close to the examples in CIEll7—1995 technical report. Hopefully, what the paper introduces can promote the implement of UGR standard and be avail to the simplification of the process of lighting quality evaluation.
