Method and system for building a lighting adaptable map of an indoor scene and using it for estimating an unknown light setting

Abstract

The disclosure relates to a computer implemented method for building a lighting adaptable map of an indoor scene, the scene comprising at least one light source and at least one surface, wherein the lighting adaptable map adapts its appearance based on a given light setting, wherein the light setting is defined by the state of each light source, comprising: obtaining first image information of the scene, where all light sources are turned on, estimating a map of the scene based on said first image information, said map comprising radiance information and light reflecting characteristics of the surfaces in the scene, detecting and segmenting individual light sources in the scene based on the estimated map, estimating the radiance contribution of each light source to the scene based on the estimated map, and building the lighting adaptable map by storing the estimated radiance contributions and combining them for any given light setting.
