A Smart Floodlighting Design System Based on Raster Images

Abstract

This article describes a system for designing floodlighting of objects using computer graphics. Contrary to the currently used visualisation tools, the developed computer application is based on the daytime photography of the object and not on its three-dimensional geometric model. The advantage of the system is the high photorealism of the simulation, with no need to create a collage of visualisation with photography. The designer uses the photometric data of luminaires, and their photometric and colourimetric parameters are defined. With the system it is possible to perform a precise lighting analysis—the distribution of illuminance and luminance—both for the entire facility and in any plane or point. The system also analyses the total installed power of a given design solution. The system application is presented as an example in the form of a case study. This example shows the features of the system and further expected directions of development.
